C. v. raman: essay on c. v. raman (760 words).

ADVERTISEMENTS:

Read this comprehensive essay on Chandrasekhar Venkata Raman (1888 A.D. – 1970 A.D.) !

The Great Indian physicist Chandrasekhar Venkata Raman, popularly known as C.V Raman, was born on 7 th November, 1888 at Trichirapalli in Tamil Nadu. His father was a physics teacher and so it was natural that Raman developed love for this subject. He was a brilliant student from the very beginning. As a brilliant and promising lad, he passed his matriculation examination at the young age of 12 from Madras University.

His parents wanted to sent him England for higher studies but his poor health did not allow it. He studied at Hindu College, Visakhapatnam and Presidency College, Madras. He obtained his post-graduation degree in physics in 1907 with the top position. During his student period he conducted many researches and published his papers in many reputed magazines.

His interest in physics was deep and lasting and so he continued his research work in his spare time in the laboratory of the Association. He published his research results in the leading journals of Calcutta, now Kolkata which were in regard to the subject of propagation of light. These original research papers were of great scientific significance.

When these came to the notice of the then Vice -Challenger of Calcutta University, Sir Ashutosh Mukharjee, he appointed him Professor of physics in the University. During his stay at the University he continued his research with much more devotion and won immense honour and recognition as a physicist.

He was elected the Fellow of the Royal Society of London in 1924. He discovered the “Raman Effect” in 1928. For it he was awarded the Nobel Prize for Physics in 1930. He became the first Indian to win this prestigious honour. With this award, his reputation increased by leaps and bounds and many Universities and institutions of repute honoured him with Ph D and D.Sc. degrees.

In December, 1927 he was busy in laboratory when the news came that the well-known physicist A.M. Compton was awarded the Nobel Prize for demonstrating that the nature of X-rays undergoes a change when passed through a matter.

This effect came to be known as the “Compton Effect.” Encouraged by this discovery, Raman continued his experiments and ultimately proved that light rays can also be scattered. His discovery enabled for the first time, the mapping of possible levels of energy gains of molecules and atoms of a substance and thus discovered their molecules and atomic structure. This discovery of the scattering of light led to the development of a simple alternative to infra-red spectroscopy, namely, Raman Spectroscopy.

Raman Effect happens when molecules of a medium scatter light energy particles known as photons. The spectrum varies with the nature of the transparent medium used to scatter the light. Raman Effect has proved to be of great scientific value and with its help the structure of more than 200 compounds has been known. He also gave us the scientific explanation for the blue colour of the sky and the ocean.

He explained that the blue color of the ocean was as a result of the scattering of sunlight by the molecules of the water. He travelled widely abroad delivering lectures about his discoveries and researches. In 1933 he became the Director of the Indian Institute of Sciences, Bangalore. In 1943 he founded the Raman Research Institute at Bangalore. He was knighted in 1927. He was awarded the Bharat Ratna in 1954 and the International Lenin Prize in 1957.

Raman was a born genius and a self-made man and scientist with deep religious convictions. His interests were wide and deep and so were his contributions to the human knowledge and development. Besides optics, he was deeply interested in acoustics—the science and study of sound.

His contributions to the mechanical theory of bowed, stringed and other musical instruments like violin, sitar, cello, piano, veena, Tanpura and mridangam have been very significant. He explained in detail how these musical instruments produce harmonious tones and notes. He died on November 21, 1970 at the ripe age of 82 at Bangalore and his mortal remains were consigned to flames in the campus of the Raman Research Institute.

What did C.V. Raman discover?

C.V. Raman discovered the Raman effect , which occurs when light that shines through a material is scattered and its wavelength changes from that of the original incident light because of its interactions with the molecules in the material.

Why did C.V. Raman win the Nobel Prize?

C.V. Raman was awarded the 1930 Nobel Prize in Physics for his discovery of the Raman effect , in which light that passes through a material is scattered and the wavelength of the scattered light is changed because it has caused an energy state transition in the material’s molecules .

Recent News

C.V. Raman (born November 7, 1888, Trichinopoly , India—died November 21, 1970, Bangalore) was an Indian physicist whose work was influential in the growth of science in India . He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect .

After earning a master’s degree in physics at Presidency College, University of Madras , in 1907, Raman became an accountant in the finance department of the Indian government. He became professor of physics at the University of Calcutta in 1917. Studying the scattering of light in various substances, in 1928 he found that when a transparent substance is illuminated by a beam of light of one frequency, a small portion of the light emerges at right angles to the original direction, and some of this light is of different frequencies than that of the incident light. These so-called Raman frequencies are the energies associated with transitions between different rotational and vibrational states in the scattering material.

Raman was knighted in 1929, and in 1933 he moved to the Indian Institute of Science, at Bangalore , as head of the department of physics. In 1947 he was named director of the Raman Research Institute there and in 1961 became a member of the Pontifical Academy of Science. He contributed to the building up of nearly every Indian research institution in his time, founded the Indian Journal of Physics and the Indian Academy of Sciences, and trained hundreds of students who found important posts in universities and government in India and Myanmar (Burma). He was the uncle of Subrahmanyan Chandrasekhar , who won the 1983 Nobel Prize for Physics, with William Fowler .

Long Essay on CV Raman 500 Words in English

Below we have given a long essay on CV Raman of 500 words is helpful for classes 7, 8, 9 and 10 and Competitive Exam Aspirants. This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.

Born at Trichinopoly in Tamil Nadu on 7th November, 1888, his father was a lecturer in Mathematics and Physics, in Mrs AV Narasimha Rao College, Visakhapatnam, and later joined Presidency College, Madras. His maternal grandfather was a Sanskrit scholar, well versed in ‘navya nyaya’ or modern logic.

So, from an early age, he was immersed in an academic atmosphere. He was a diligent student. He entered the Presidency College, Madras, in 1902, and in 1904 passed his BA examination, winning the first place and a gold medal in Physics. In 1907, he gained his MA degree, obtaining the highest distinctions. His earliest researches in optics and acoustics—the two fields of investigation to which he dedicated his entire career were carried out while he was a student. Since at that time a scientific career did not appear to offer the best possibilities, Raman joined the Indian Finance Department in 1907. Though the duties of his office took most of his time, Raman found opportunities for carrying on experimental researches in the laboratory of the Indian Association for the Cultivation of Sciences at Calcutta.

In 1917, he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. Raman’s main research was focussed on acoustics and musical instruments, and led to his election as fellow of the Royal Society in 1924. It was during a trip to England in 1921 that he was fascinated by the blue colour of the Mediterranean.

With a very simple experiment, he convinced himself that the blue colour of the sea was not only due to the reflection of the sky, as proposed by Lord Rayleigh, but mainly due to the scattering of light by water molecules. On his return to Calcutta, he began a systematic study of the scattering of light by different liquids, culminating in the discovery of a totally new kind of radiation, predicted by the quantum theory and named after him.

There Raman radiations carry vital information about the internal structure of the scattering molecules, and have proved to be of immense importance in studying molecular structures. His efforts finally paid off when he was awarded the Nobel Prize in Physics in 1930, the first to be ever won by an Indian. Thereafter, he became the Honorary Secretary of the Indian Association for the Cultivation of Sciences. After 15 years in Calcutta, he became Professor at the Indian Institute of Science at Bangalore (1933-1948) and in 1948, he became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he was the Editor.

Raman sponsored the establishment of the Indian Academy of Sciences and served as its President since its inception. He was also the President of the Current Science Association, Bangalore, which publishes Current Science. (India)

Raman has done credible work in his field and his early memoirs appeared as Bulletins of the Indian Association for the Cultivation of Sciences. These dealt with the maintenance of vibrations and the theory of musical instruments of the violin family. In 1922, he published his work on the ‘Molecular Diffraction of Light’, the first of a series of investigations with his collaborators which ultimately led to the discovery, on 28th February, 1928, of the radiation effect, which is named after him. This work bagged him the 1930 Nobel Prize in Physics.

Some other investigations which propelled the world of science during his time were the experimental and the theoretical studies on the diffraction of light by acoustic waves of Ultrasonic and Hypersonic frequencies. In 1932, he and Suri Bhagavantam discovered quantum photon spin. During his term at IISc, he admitted the talented electrical engineering student, GN Ramachandran, who went on to become a recognised X-ray crystallographer.

Sir Chandrasekhara Venkata Raman

Biographical.

His earliest researches in optics and acoustics – the two fields of investigation to which he has dedicated his entire career – were carried out while he was a student.

Since at that time a scientific career did not appear to present the best possibilities, Raman joined the Indian Finance Department in 1907; though the duties of his office took most of his time, Raman found opportunities for carrying on experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta (of which he became Honorary Secretary in 1919).

In 1917 he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. After 15 years at Calcutta he became Professor at the Indian Institute of Science at Bangalore (1933-1948), and since 1948 he is Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he is the Editor. Raman sponsored the establishment of the Indian Academy of Sciences and has served as President since its inception. He also initiated the Proceedings of that academy, in which much of his work has been published, and is President of the Current Science Association, Bangalore, which publishes Current Science (India) .

Some of Raman’s early memoirs appeared as Bulletins of the Indian Associationfor the Cultivation of Science (Bull. 6 and 11, dealing with the “Maintenance of Vibrations”; Bull. 15, 1918, dealing with the theory of the musical instruments of the violin family). He contributed an article on the theory of musical instruments to the 8th Volume of the Handbuch der Physik , 1928. In 1922 he published his work on the “Molecular Diffraction of Light”, the first of a series of investigations with his collaborators which ultimately led to his discovery, on the 28th of February, 1928, of the radiation effect which bears his name (“A new radiation”, Indian J. Phys. , 2 (1928) 387), and which gained him the 1930 Nobel Prize in Physics.

Other investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. In 1948 Raman, through studying the spectroscopic behaviour of crystals, approached in a new manner fundamental problems of crystal dynamics. His laboratory has been dealing with the structure and properties of diamond, the structure and optical behaviour of numerous iridescent substances (labradorite, pearly felspar, agate, opal, and pearls).

Among his other interests have been the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision.

Raman has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected a Fellow of the Royal Society early in his career (1924), and was knighted in 1929.

This autobiography/biography was written at the time of the award and first published in the book series Les Prix Nobel . It was later edited and republished in Nobel Lectures . To cite this document, always state the source as shown above.

Water: The Elixer Of Life By C. V. Raman – Summary and Questions

Table of Contents

Water: The Elixer Of Life – C.V.Raman

Introduction: Water is a vital ingredient for survival of all living beings. Imagine a day without water no water to drink, wash, or to cook! People can survive without food for days but not without water. About 70% of earth’s surface is covered with water. Of this 97% is saline and 2% is fresh which is present in the form of ice caps, glaciers, icebergs or in the atmosphere. Only 1% can be used for drinking. We are heading towards a freshwater crisis that is leading to poor access to safe water for millions of people. Hence, conserving water has become the need of the hour, along with an efficient management system, to ensure a steady supply for the future.

Water, an elixir of life

Humankind has always searched in vain for an imaginary elixir of life, the divine amrita. A draught of this elixir was thought to confer immortality <em>Immortality</em> is the indefinite continuation of a person's existence, even after death. It is the quality or condition of being immortal.  It also means enduring fame. " data-gt-translate-attributes='[{"attribute":"data-cmtooltip", "format":"html"}]' tabindex=0 role=link>immortality . But Raman feels that the true elixir of life is water. This single liquid can change the entire scene. He remembers that he was standing on the line which separates the Libyan Desert from the valley of the Nile in Egypt. On one side was a vast area covered with sand and without a speck of green or a single living thing. On the other side was one of the greatest, most fertile and densely populated areas. It was teeming with life and vegetation. The only thing which made the difference was water. It was the water of the river Nile. Geologist tells that the entire soil of river, Nile is the creation of the river itself. Its ancient civilization was created and sustained by the life-giving water of the Nile.

We take granted this common substance in everyday life. But we forget that water is the most potent and wonderful thing on the earth. It has played a very important role In shaping the course of earth’s history. It continues to play the leading role in the drama of life on earth. Nothing can add so much to the beauty of the countryside as water. In south India, the rain-fed tanks are very common. They are shallow but the bottom of the tank is not visible due to silt-laden water. These tanks play a vital role in south India agriculture. Much of rice is grown under them.

One of the most remarkable facts about water is its power to carry silt in suspension. This suspension is the reason for the different colours of the water in a rain-fed tank. Swiftly flowing water can carry fairly large and heavy particles. The finest particles remain with the water and are carried to a large distance. When silt-laden water mixes with the saltwater of the sea, there is rapid precipitation of the suspended matter. The colour of the water changes successively from the muddy red or brown of silt through varying shades of yellow and green finally to the blue of the deep sea. A large land is formed by silt thus deposited. Such land is very fertile. The flow of water plays a great part in this process; sometimes it can be destructive also.

Water is the basis of all life. Every animals and plant contain water in this body. No activity is possible without water. Water is necessary for animal life. The moist in the soil is necessary for the growth of plants and trees. So, the conservation and utilization of water is most important for human welfare.

A vast area of land could be turned into a fertile and prosperous country by courageous and well-planned action. The systematic planting of suitable trees is the urgent need of India. Such plantation would, directly and indirectly, prove a source of wealth to the country. They would check soil erosion and conserve the rainfall of the country. Water is the commonest of liquid, but it is also the most uncommon of liquid with amazing properties. These properties are responsible for its unique power of maintaining animal and plant life. The investigation of the nature and properties of water is, therefore, of the highest scientific interest.

Questions and Answers

Ans. Water is the true elixir of life. This is a common substance. So, we take it granted in our everyday life. It is the most wonderful thing on Earth. It continues to play a leading role in the drama of life on Earth.

The conservation and utilization of water is fundamental to human welfare. One of the most remarkable facts about water is its power to carry silt suspension. Our agriculture depends on seasonal rainfall. So, collection and utilization of rainwater is very important. Water is the commonest of the liquids. These uncommon properties are responsible for its unique power of maintaining animal and plant life.

Question.2. Write about the power and beauty of the element, water.

One of the most remarkable facts about water is its power to carry silt in suspension. The flow of water plays a great role in the geographical process. It can sometimes play a destructive role and wash away the soil. Great tracts of land have been formed by silt deposited by water. The problem of soil erosion is caused by water. Vast areas of land could be turned into fertile or infertile. This is the power and beauty of water.

The sudden burst of excessively heavy rain results into a large run of surplus water which causes soil erosion. The slope of land, removal of the natural protective coat of vegetation, ruts for flow of water with speed and no check to such flow are also the causes for soil erosion.

Question.4. What are the usual measures used to check soil erosion?

Vast areas of land could be turned into a fertile and prosperous country by well-planned action. The systematic planting of suitable trees in every possible place is most urgent in India. They would check soil erosion and conserve the rainfall of the country.

Ans. C.V. Raman gives the example of rain-fed tanks which play a very vital role in south Indian agriculture. In Mysore, much of the rice is grown under them. The colour of the water in rain-fed tanks changes according to the land from which the water comes. Swiftly flowing water can carry large and heavy particles. The finest particles remain floating in the water. Large areas of land can be converted into fertile land due to silt-laden water.

Collection and utilization of rainwater is very important because our Indian agriculture depends on rainfall. Much of the rainwater flows down into the river and the sea. So a large quantity of water is lost. The proper use of this flowing water is a great national problem. Planting of trees is urgent need of India. They would help to save the rainwater of the country from flowing away to waste.

The early life of CV Raman

Born on November 7, 1888, in Tiruchirappalli, Tamil Nadu, Raman displayed a prodigious intellect from an early age, finishing his secondary education by the age of 11.

He graduated with a Bachelor of Arts degree from Presidency College, Madras, in 1904, and subsequently completed his Master’s in Physics in 1907.

• Despite beginning his career in the Indian Finance Department as a civil servant, Raman’s passion for science never waned.
• He conducted research at the Indian Association for the Cultivation of Science (IACS) in Kolkata during his spare time, which led to significant discoveries in acoustics and optics.

CV Raman made his first trip to London in 1921, where his reputation in the study of optics and especially acoustics was already known to the English physicists J. J. Thomson and Lord Rutherford.

• Raman’s specialty had been the study of the vibrations and sounds of stringed instruments such as the violin, the Indian veena, and tambura, and two uniquely Indian percussion instruments, the tabla, and the mridangam.

But it was the return trip from London to Bombay aboard the SS Narkunda that would change forever the direction of Raman’s future.

• During the fifteen-day voyage, his restless and probing mind became fascinated with the deep blue color of the Mediterranean.
• Unable to accept Lord Rayleigh’s explanation that the color of the sea was just a reflection of the color of the sky, Raman proceeded to outline his thoughts on the matter while still at sea and sent a letter to the editors of the journal Nature when the ship docked in Bombay.

A short time later Raman was able to show conclusively that the color of the sea was the result of the scattering of sunlight by the water molecules.

• Ironically, it was the same argument that Rayleigh had invoked when explaining the color of the sky – the blue was the result of the scattering of sunlight by the molecules in the air.

Nobel Prize and the Raman Effect

CV Raman’s most celebrated discovery, the Raman Effect, came in 1928. It demonstrated that when light traverses a transparent material, some of the deflected light changes wavelength and amplitude.

• This discovery was groundbreaking because it confirmed the quantum nature of light and was the first strong evidence of the quantum behavior of molecules.
• Raman used a simple apparatus to show that when light passes through a transparent substance, it scatters, and the scattered light contains frequencies not present in the original light, a phenomenon that could not be explained by classical physics.

For this discovery, he was awarded the Nobel Prize in Physics in 1930, becoming the first Asian and the first non-white to receive a Nobel Prize in the sciences.

What is the Raman effect?

The Raman Effect occurs when light interacts with the molecules of a material, causing a change in the energy and wavelength of the scattered light.

• When monochromatic light (light of a single wavelength, usually from a laser) is directed at a material, most of the light scatters elastically (Rayleigh scattering), meaning it retains its original energy and wavelength.
• However, a small fraction of the light (approximately 1 in 10 million photons) scatters inelastically, either gaining or losing energy in the process. This inelastic scattering is the Raman Effect.

Stokes and Anti-Stokes Scattering

The energy change in the scattered light corresponds to the vibrational energies of the molecules in the material.

• If the scattered light loses energy (shifts to a longer wavelength), it is called Stokes scattering.
• Conversely, if the scattered light gains energy (shifts to a shorter wavelength), it is called Anti-Stokes scattering.
• The difference in energy between the incident and scattered light directly relates to the vibrational energy levels of the molecules in the sample.

The discovery of the Raman Effect was a milestone in experimental physics and quantum theory.

• It provided the first experimental evidence of the quantum nature of light and molecules, supporting the theoretical predictions of quantum mechanics.
• The Raman Effect showed that light-matter interactions could result in the exchange of energy, leading to a deeper understanding of molecular energy levels and the electromagnetic spectrum.

Application of Raman effect

In the first seven years after its discovery, the Raman Effect was the subject of more than 700 papers in the scientific literature, mostly by physicists who were using the technique to study the vibration and rotation of molecules and relating those phenomena to the molecular structure.

By the late 1930s, the Raman Effect had become the principal method of non-destructive chemical analysis for both organic and inorganic compounds.

• The unique spectrum of Raman scattered light for any particular substance served as a “fingerprint” that could be used for qualitative analysis, even in a mixture of materials.
• Raman spectroscopy could be applied not only to liquids but also to gases and solids.
• The use of Raman spectroscopy as a basic analytical tool changed sharply after World War II.
• During the war, infrared spectroscopy was enhanced by the development of sensitive detectors and advances in electronics.

Other applications:

• Material Science : It helps in characterizing materials, understanding their structure, and studying phase transitions.
• Biological Studies : Raman spectroscopy is used in the medical field to diagnose diseases, analyze biochemical changes in cells, and study drug interactions at the molecular level.
• Pharmaceuticals : It assists in drug development and quality control by identifying the molecular composition and crystalline forms of drugs.
• Environmental Science : It is employed in detecting pollutants and analyzing environmental changes.

Academic and Research Contributions

After his Nobel win, Raman’s reputation and influence grew. He served as the director of the Indian Institute of Science (IISc) in Bangalore from 1933 to 1937.

He established the Raman Research Institute in Bangalore in 1948, where he worked until he died in 1970.

He also founded the Indian Journal of Physics in 1926, of which he is the Editor. Raman sponsored the establishment of the Indian Academy of Sciences and has served as President since its inception.

His research at these institutions spanned various domains of physics, including crystal dynamics, musical instruments, and the properties of diamonds.

Raman’s legacy is not just in his scientific discoveries but also in his role as a leader in Indian science. He was instrumental in promoting scientific research in India, inspiring generations of scientists.

Despite facing several challenges, including limited resources and recognition from the global scientific community initially, Raman’s perseverance and dedication to science shone brightly. His work laid the groundwork for numerous scientific advancements, including the study of molecular energy levels, chemical analysis techniques, and even the investigation of quantum mechanics.

Sir CV Raman passed away on November 21, 1970, leaving behind a rich legacy of scientific inquiry and discovery. His life and work continue to inspire scientists around the world, underscoring the importance of curiosity, perseverance, and the relentless pursuit of knowledge.

Sir C. V. Raman: The Pioneer Of Modern Science In India  Blogs Home

• 07 Nov 2022

At a time of distress when the entire nation was struggling to be free from the shackles of oppression and cruelty, a man of science was busy making space for India on the globe.

“Look at the resplendent colours on the soap bubbles! Why is the sea blue? What makes diamond glitter? Ask the right questions, and nature will open the doors to her secrets.”

These are the words of Sir Chandrasekhara Venkata Raman, also known as Sir C V Raman, whose inquisitiveness and incessant efforts to find the answers made him the first Asian physicist to receive the Nobel prize in 1930. 7th November marks the birth anniversary of this revered scientist who discovered the Raman Effect. His discovery enabled the scientific community to move forward and better understand various natural phenomena.

Sir C V Raman was born in 1888 in Tiruchirappalli, Tamil Nadu. His father was Chandrashekhar Ramanathan. He was a lecturer of Mathematics and Physics at the Presidency College at the University of Madras. He graduated at the age of 16 from the same college. He was a brilliant student and a gold medalist. After obtaining Masters' in Physics, he secured a government job in Indian Finance Department. He continued experimental research in acoustics and optics in the laboratory of the Indian Association for the Cultivation of Science (IACS). He also published his work in leading Physics journals.

In 1917, he left his government job and became a Palit Professor of Physics at the University of Calcutta. He continued studying acoustics, the sounds of stringed instruments like violin and veena and percussion instruments like tabla and mridangam. His work earned him a good reputation among his peers in the country and internationally. On his first trip to London in 1921, he received a warm welcome from English Physicists J. J. Thomson and Lord Rutherford.

While returning to India from London via sea route, the blue colour of the sea caught his attention. Dissatisfied with Lord Railey’s explanation that the colour of the sea was blue due to the reflection of the colour of the sky, he decided to investigate the reason behind it. With his mentee K. S. Krishnan , he started studying light scattering.

His sincerity, dedication, and contribution towards the discipline of physics got recognition from the Royal Society of London when he was elected a fellow of the society in 1924. He got invited to the California Institute of Technology (Caltech) in the United States by Nobel Laureate Robert Millikan, where he spent four months studying the scattering of light. On 28th February 1928, he finally got his answer when he discovered Raman Effect, according to which the light changes its wavelength and frequency when it gets deflected by molecules. The day has been commemorated as National Science Day every year since 1987

Sir Raman was already a renowned name in the field of science but discovering the Raman effect strengthened his position in the community. He received a knighthood from the Royal Society of London in 1929, and the following year he became the first Indian scientist to be honoured with the Nobel Prize. He also headed the Indian Institute of Science (IISc), Bangalore as the first Indian director.

Sir Raman was educated in India; he did most of his research work here and went on to earn the reputation of an internationally celebrated physicist. Ernest Rutherford, who discovered the nucleus, referred to Raman’s Spectroscopy in his presidential address to the Royal Society of London.

Sir Raman dreamt of building a society in India like the Royal Society of London and other entities in the world to inculcate scientific temperament in the Indian youth. In 1934 he founded the Indian Academy of Science (IAS) in Bangalore to further the cause of science. After retiring from IISc, Sir Raman founded Raman Research Institute (RRI) to continue his research. He remained the director of RRI until his death on 21st November 1970.

He expressed his disappointment in Indian talent leaving the country to find better opportunities abroad when he said:

“My life has been an utter failure. I thought I would try to build true science in this country, but all we have is a legion of camp followers for the west.”

But he remained open to working with western physicists like Max Born and Erwin Schrodinger, both of who were Nobel Laureates. He persuaded German scientist Max Born to come to India and work for the country. He stayed for some time at IISc, but Sir Raman’s efforts to prolong his stay could not fructify.

Sir C. V. Raman was honoured on numerous platforms for his incredible contribution to advancing the sciences. After India became independent, he became the first national professor of India. He was awarded Bharat Ratna in 1954. He remains one of the few recipients to receive both the Bharat Ratna and the Nobel Prize. He received Lenin Peace Prize in 1957 in Kremlin. Several buildings and roads are also named after him in Russia.

Today, the Raman effect is used in medicine, surgery, and medical diagnosis like cancer detection. It is being used in remote sensing, geology, and mineralogy. It is used for ensuring quality control in the pharmaceutical industry. Police are also using it for forensic work. The most visible public use of Raman spectroscopy can be seen at airports, metro stations, malls, or other places of security where scanners are used to detect explosives and drugs.

Sir C. V. Raman’s discovery has proved to be a significant stepping stone to the world of science. He left us half a century ago, and his discovery will also be a century old in a few years. Still, his ideas will always remain relevant and encourage curious minds to unravel the secrets of nature.

CV Raman: The Renowned Scientist Behind the Discovery of Raman Effect!

Sir Chandrasekhara Venkata Raman (CV Raman) was an Indian scientist and physicist. Born on 7th November 1888, his contribution to the field of science got him a Nobel Prize in Physics in 1930. He discovered the ‘ Raman Effect ’, which is a unique form of ‘modified scattering of light’. He was awarded Fellowship of Royal Society of London in 1924, along with a Knights Bachelor in 1930.

Born in a family of Hindu Tamil Brahmins, he was one of the eight siblings. He displayed his higher level of intelligence at a very young age, making him a child prodigy. 

He completed his secondary school at 11 and higher secondary school at 13 years of age. By 16, he graduated Physics Bachelor’s degree with honours, as a topper of his class. He had published his first research paper on ‘diffraction of light’, even before his graduation. He then went on to pursue his master’s degree. By the age of 19, he was appointed as Assistant Accountant General in the Indian Finance Service, Calcutta.

The IACS (Indian Association for the Cultivation of Sciences) was the first research institute in India. This institute allowed CV Raman to research extensively about acoustics and optics. This research got him his well-deserved fame among the international scientific community. Eventually, he was offered the position of ‘Palit Professor’ for the Physics Dept. at the University of Calcutta’s Rajabazar Science College.

When he visited Europe for the first time, watching the Mediterranean Sea inspired him. He sought to disprove that Rayleigh-scattered light is the reason why the sea was observed to be blue-colored. In 1923, Compton proved that EM waves could also be described as particles . 

When Ramanathan learnt this in 1927, he continued his research with K. S. Krishnan. During his research with his associate K. S. Krishnan, Raman discovered interesting properties of light.

K. S. Krishnan observed that all types of liquids produced polarised fluorescence. This was within the visible spectrum of light. CV Raman noted this, called it modified scattering, and sent the manuscript to ‘Nature’ scientific magazine. 

Raman invented a spectrograph for detecting this phenomenon. They placed a violet filter on sunlight and scattered it through a liquid. This produced Rayleigh’s scattered light and a weak light of different colour. They then placed a green filter and noticed green light scattered by the liquid. This was Raman’s scattered light. It was a secondary type of radiation, and more than 60 other liquids displayed the same output. This discovery was one of the initial reliable proofs of the ‘quantum nature of light’.

(1888–1970). The Indian physicist C.V. Raman helped the growth of science in his country. He received the Nobel Prize for Physics in 1930 for the discovery that when light passes through a transparent material, some of the light changes in wavelength. This phenomenon is now called Raman scattering.

Chandrasekhara Venkata Raman was born on November 7, 1888, in Trichinopoly, India. He became professor of physics at the University of Calcutta in 1917. While studying the scattering of light in various substances, Raman made an important discovery in 1928. He found that when a beam of light of one frequency passes through a transparent substance, a small portion of the light emerges at right angles to the original direction. Some of this light is of different frequencies than that of the original light beam. These so-called Raman frequencies are the energies associated with transitions between different rotational and vibrational states in the scattering material.

Raman was knighted in 1929, and in 1933 he moved to the Indian Institute of Science at Bangalore as head of the department of physics. In 1947 he was named director of the Raman Research Institute there. In 1961 Raman became a member of the Pontifical Academy of Sciences. He contributed greatly to increasing the vitality of nearly every Indian research institution in his time. Raman founded the Indian Journal of Physics and the Indian Academy of Sciences and trained hundreds of students who found posts in universities and government in India and Myanmar (Burma). Raman died on November 21, 1970, in Bangalore. He was the uncle of Subrahmanyan Chandrasekhar , who was a cowinner of the 1983 Nobel Prize for Physics.

This article includes instances from his birth, early life, career, various achievements, and more.

C.V Raman: Biography

C.V. Raman, or Chandrasekhara Venkata Raman, was born on November 7, 1888, at Tiruchirappalli in southern India. His father was a lecturer in mathematics and physics. At a young age, he was exposed to an academic environment. His contribution to science and innovative research helped India and the world. 

Dr. Chandrasekhara Venkata Raman (C.V. Raman): Early Life and Family

Dr. C.V. Raman was born on November 7, 1888, in a South Indian Brahmin family in Tiruchirappalli, Tamil Nadu. His father's name was Chandrasekhara Ramanathan Iyer. He was a lecturer in mathematics and physics at a college in Vishakhapatnam. His mother's name was Parvathi Ammal.

C. V. Raman has been an intelligent student since his early childhood. At the age of 11, he passed his matriculation and 12th grade on a scholarship. In 1902, he joined the Presidency College and received his graduate degree in 1904. At that time, he was the only student who received the first division. He has a Master's in Physics from the same college and broke all the previous records.  In 1907, he married Lokasundari Ammal and had two sons, namely Chandrasekhar and Radhakrishnan.

Dr. Chandrasekhara Venkata Raman (C.V. Raman): Career

Because of his father's interest, he appeared for the Financial Civil Services (FCS) examination and topped it. In 1907, he went to Calcutta (now Kolkata) and joined as an assistant accountant general. But in his spare time, he went to the laboratory to do research at the Indian Association for Cultivation of Sciences. Let us tell you that, his job was very hectic, and he also continued his research work at night due to his core interest in science.

Though the facilities available in the laboratory were very limited, he continued his research and published his findings in leading international journals, including 'Nature', 'The Philosophical Magazine', 'Physics Review', etc. At that time, his research was focused on the areas of vibrations and acoustics.

He got an opportunity to join the University of Calcutta in 1917 as the first Palit Professor of Physics. After 15 years at Calcutta, he became a Professor at the Indian Institute of Science at Bangalore from 1933 to 1948 and since 1948, he has been the Director of the Raman Institute of Research at Bangalore which was established and endowed by him only.

Dr. Chandrasekhara Venkata Raman (C.V. Raman): Works and Discovery

He established the Indian Journal of Physics in 1926 where he was the editor. He also sponsored the establishment of the Indian Academy of Sciences and served as the President since its inception. He was the President of the Current Science Association in Bangalore, which publishes Current Science (India).

In 1928, he wrote an article on the theory of musical instruments for the 8th Volume of the Handbuch der Physik. He published his work on the "Molecular Diffraction of Light" in 1922 which led to his ultimate discovery of the radiation effect on February 28, 1928, and earned him the Nobel Prize in Physics in 1930. He became the first Indian to receive a Nobel Prize.

Other research carried out by Dr. C.V. Raman was on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies and the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light.

In 1948, he also studied the fundamental problems of crystal dynamics. His laboratory has been dealing with the structure and properties of diamonds, and the structure and optical behaviour of numerous iridescent substances like pearls, agate, opal, etc.

He was also interested in the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision.

No doubt, he was honoured with a large number of doctorates and memberships in scientific societies. In 1924, he was also elected as a Fellow of the Royal Society early in his career and was knighted in 1929.

As briefly described he is best known for discovering the 'Raman Effect' or the theory related to the scattering of light. He showed that when light traverses a transparent material, some of the deflected light changes its wavelength.

Dr. Chandrasekhara Venkata Raman (C.V. Raman): Awards and Honours

- In 1924, he was elected as a Fellow of the Royal Society early in his career and was knighted in 1929.

- He won the Nobel Prize in Physics in 1930.

- He was awarded the Franklin Medal in 1941.

- He was awarded the Bharat Ratna in 1954, the highest civilian award in India.

- In 1957, he was awarded the Lenin Peace Prize.

- The American Chemical Society and the Indian Association for the Cultivation of Science in 1998 recognised Raman's discovery as an International Historic Chemical Landmark.

- On 28 February every year, India celebrates National Science Day to commemorate the discovery of the Raman Effect in 1928 in his honour.

In 1970, he received a major heart attack while working in the laboratory. He took his last breath at the Raman Research Institute on 21st November 1970.

Dr. C.V. Raman was one of the great legends from India whose hard work and determination made India proud and became the first Indian to receive a Nobel Prize in Physics. He proved that, if a person wants to pursue his/her desires nobody can stop. His interest in science and dedication towards research work made him discover the Raman Effect. He will always be remembered as a great Scientist, Physicist, and Nobel laureate.

• C V Raman Biography

Writing a Biographical Essay of a Historical Figure

Sir Chandrasekhara Venkata Raman, was an Indian physicist who won the Nobel Prize in Physics in 1930 for his work on light scattering and the discovery of a new form of scattering called Raman scattering or the Raman effect. The compositions of solids, liquids, and gases can all benefit from this effect. It can also be used to diagnose diseases and track manufacturing processes. 

Biography is an account of a person’s life by another person. It is a descriptive work written in detail. Biographical pieces can be in various forms, like a video or book and they can be of any length, like a book or an essay. An authorized biography is written with the permission of the subject and an unauthorized one is not. However, biographies of historical figures written for purely academic purposes do not require consent from the subject or people who hold the rights of consent for the subject.

Choosing the Right Level

Biographies can be written by students of all classes. The higher the class, the more details go into the essay. The biography by a fifth-grader will be smaller and less detailed than that written by a ninth-grader. The demand for making it more interesting and decorating it with aptly placed figures of speech grows with grade.

Choosing the Right Source

Biography is not fiction or a made-up story. It is the arrangement of boring dates and facts into a beautiful landscape that would be the subject’s life. For the facts to be accurate and true, trustworthy sources must be consulted, like a known book or reliable websites that contain life information.

Choosing the Right Information

Having selected the right source of information, it can get mind-boggling to choose what information to keep and what not to mention in the essay. It is better to have too much information than too little so that the best out of them can be chosen. A biography should answer some basic questions about the person. The place and date of his birth and death. Information about his immediate family. Important milestones of his life, like schooling, occupation, marriage, kids, appointments, or discoveries. His accomplishments during his lifetime. And then the legacy he leaves behind, like his impact on society or education and the historical significance.

How to Arrange the Information?

Biographies are descriptions of someone’s life, so setting the tone and making it sound interesting relies freely on the writer’s shoulders. The student can make life sound fun and lively, or gripping and intense. This is where the talent of a writer shines through, so use all of the writing tools at hand and make the best of them.

The Person Behind the Facts

The personality of the subject should shine through the essay. Select appropriate adjectives to build upon the character of the person. If interesting anecdotes highlight the kind of person he was, use them to build upon his personality.

Legacy in Conclusion

The achievement of his life and his notable works need to be mentioned, as well as how he affects posterity. In conclusion, the importance of his work and legacy should be highlighted.

It should be remembered that however tempting it feels to include interesting details and fun facts, the word limit should be kept in mind. This is what should rule which facts go and which do not in the essay. The introduction, body, and conclusion need to be clearly arranged. A biographical essay is not a story-telling spree, so the spirit of an essay should be intact.

The best essays are easy to read and the flow from one part to another is seamless. It might sound contradictory to keep a seamless flow while keeping the three parts of an essay demarcated, but it is not impossible and this is the delicate balance that can only be achieved by persistent practice. Language is not much different from Maths or Science in this aspect – practice makes perfect.

Information About C V Raman

Sir C V Raman’s birthday- November 7, 1888

Sir C V Raman’s death day- November 21, 1970

Alma mater- The University of Madras (M.A.)

Known for Raman effect

Spouse- Lokasundari Ammal (1908–1970)

Children- Chandrasekhar Raman and Venkatraman Radhakrishnan

About C V Raman’s Family and Background

Chandrasekhara Venkata Raman was born to a Tamil Brahmin family in Tiruchirapalli, Tamil Nadu, on November 7, 1888. Raman's forefathers were agriculturists who settled in the Tanjore district near Porasakudi Village and Mangudi. Chandrasekhara Iyer, his father, attended a school in Kumbakonam and graduated with honours in 1881. He eventually earned a Bachelor of Arts degree in Physics from Tiruchirapalli's Society of the Promotion of the Gospel College in 1891. In the same college, Chandrasekara became a lecturer. He married Parvathi Ammal after passing the Matriculation exam and they had eight children: five sons and three daughters. Chandrasekaran, Raman's father, moved to Visakhapatnam when he was four years old to work as a lecturer at Mrs. A.V. Narasimha Rao College. He taught Physics, arithmetic, and physical geography at the university. Chandrasekaran was regarded as physically and mentally powerful due to his involvement in athletics, physical culture, and Indian Carnatic music, among other things. Raman, unlike his father, was not physically powerful, but he was a brilliant thinker. He excelled in school and displayed early signs of exceptional ability, receiving praise from his teachers as well as numerous prizes and scholarships. While still in school, Raman developed an interest in Physics. He once designed a dynamo on his own and was fascinated with how physical principles and machines worked. C. V. Raman graduated from high school at the age of eleven, receiving first place in the Matriculation Examination (top marks). He then enrolled in the AVN College to prepare for the Intermediate Exam. He received more accolades this time, and he received top scores on the university test. In 1903, he received a scholarship to study for a BA degree at the Presidency College in Chennai (then Madras), where he was the youngest student. At the time, the Presidency College was the best in Southern India. When Raman was in college, the majority of his professors were Europeans. Raman's interest in Physics grew even stronger during this period, and he also developed a strong liking for English. Raman earned first place in the university's BA exams in 1904, and gold medals in English and Physics. Raman's teachers encouraged him to continue his education in England, but the Madras Civil Surgeon refused, arguing that the young Raman was too weak to endure the English climate. Raman, on the other hand, completed his MA in Physics at Presidency College and did not travel abroad until he was thirty-three years old.

About C V Raman’s Early Career and Marriage

In January 1907, Raman sat for and passed his Master's examination, earning top marks and a slew of awards and prizes. While he desired to focus on science (particularly research), there were no research opportunities in India (specifically for Indians). Owing to his deteriorating health at the time, he was unable to travel to England. As a result, Raman's thoughts turned to work for the government, which is known to be clean, stable, and even prestigious. Even in this situation, he desired to enter the prestigious Indian Civil Service (ICS), the highest level of government service, but this meant training in England and taking the exam there—an option that was also ruled out due to medical reasons. The Financial Civil Service (FCS), where Raman's brother C.S. Iyer was already a member, which was his next preference. The FCS served as a forerunner to today's Indian Audit and Accounts Service. Raman passed the FCS examination in 1907 and married Lokasundari before taking up an official job. This period of his life unfolded unusually. Typically, parents arranged Indian marriages, which includes finding a suitable horoscope match for their infant. This included looking at the positions of the stars on their birth date, as well as other horoscopic statistics.  The boy and his parents then pay a visit to the girl's house to see if she likes them; during this period, the girl is normally asked to give a musical performance. The date for their marriage is fixed if all arrangements are in agreement and the girl's family provides adequate dowry. Raman's marriage went in a different direction. Mr. Ramaswamy Sivan, a freemason, theosophist, and radical thinker, was a friend of Raman's as a college student. Mr. Sivan's house was a frequent stop for Raman, and one day he heard music from an Indian classical instrument, the veena, played by Lokasundari, Sivan's sister-in-law, who was visiting from Madurai. Lokasundari was a natural at playing the veena, and Raman was instantly drawn to her. Sivan discussed this idea with Raman, who immediately accepted it since Lokasundari was of marriageable age at the time and her family was looking for a suitable groom. Raman then continued to seek permission from his parents. However, it was later discovered that Lokasundari, thought of the same caste as Raman (Brahmin), belonged to a separate subset—a match that was strictly forbidden at the time. Raman's father, who is a rather liberal man, agreed that Raman could choose his bride, even if she came from a different subset. The rest of the family, including Raman's mother, was unhappy, however. Despite these challenges, Raman followed his heart and kept on doing things his way. In mid-1907, Raman was appointed Assistant Accountant-General in Calcutta, even though he was still a teenager. His pay, including the marriage allowance, was Rs. 400 at the time. Raman and Lokasundari set out for Calcutta, the capital of British India at the time. Raman took advantage of Calcutta's vibrant and scientific environment, allowing him to fully articulate his scientific creativity—Calcutta was then regarded as the East's premier science city. Raman was sent to Nagpur and Rangoon in addition to Calcutta; no matter where he was posted, Raman still found a way to perform experiments at home.

C V Raman Contribution to Science

Raman productively used the time he had with Professor Jones while studying Physics at Presidency College, designing and creating experiments to address the boundless questions he had. Only the most basic laboratory instruments (enough for classwork) were available in the Physics lab at the time, but Raman made use of them all. Raman's questions were frequently those for which there were no answers in the literature. As a result, the nature of science came naturally to him, prompting him to perform experiments throughout his life. Raman experimented with asymmetric diffraction of light though he was well aware of light in a wave shape and the principle of diffraction. Professor Jones was given his observations on this experiment, which he collected and gave to him for feedback. Professor Jones, on the other hand, remained silent for many months. Raman was aware of the Philosophical Magazine at the time, possibly those subscribed to by the Connemara Public Library, which was about five kilometers from Presidency College (it is not certain how Raman came to know of this magazine). This paper was written in 1906, and Raman, who was only 18 at the time and had not yet graduated from high school, was the sole author with no acknowledgments. Raman's achievement was all the more remarkable because Presidency College was not a research institution, and Raman's paper was the first to emerge from there. Almost immediately after Raman's first publication, Johns Hopkins University's R.W. Wood published another. Wood later sent a cable to Nature announcing the Raman Effect's discovery. Raman left the government in 1917 to take up the newly established Palit Professorship in Physics at the University of Calcutta. Simultaneously, he continued his study at the IACS, where he eventually rose to the position of Honorary Secretary. Raman referred to this period in his career as his "golden age." At the IACS and the University of Calcutta, he was surrounded by a group of gifted students. In 1929, he presided over the 16th session of the Indian Science Congress. Raman worked on the acoustics of musical instruments in addition to his Nobel Prize-winning work on light scattering. Based on superposition velocities, he developed a theory of transverse vibration of bowed strings. In comparison to Helmholtz's method, this does a great job of describing bowed string vibration. He was also the first to explore the harmonic essence of Indian drum sounds like the tabla and mridangam. Raman was appointed director of the newly established Indian Institute of Science (IISc) in Bangalore in 1933. The IISc was established in 1909 with the aim of conducting original research and providing science and engineering education. Before Raman's appointment, all of IISc's directors, as well as the majority of its faculty, were British. He remained a Professor of Physics for another two years. The new government of Independent India named him the country's first National Professor in 1947. In 1948, he retired from the Indian Institute of Science and a year later founded the Raman Research Bangalore, Karnataka, where he served as director until he died in 1970.

C V Raman’s Discovery

Raman was awarded the Nobel Prize in Physics in 1930 for his research on light scattering and the discovery of the Raman effect. The inelastic scattering of a photon is known as "Raman scattering" or "Raman effect." This phenomenon is the basis for Raman spectroscopy.

What led to C V Raman’s Invention of Raman Effect?

C V Raman Discovery of the Physics of Musical sound- Understanding the Physics of musical Sound was one of Raman's passions. The Sensations of Tone by Hermann Von Helmholtz, which he came across when he entered IACS, inspired him. Between 1916 and 1921, he researched and published a lot of his observations. Based on the superposition of velocities, he developed the principle of transverse vibration of bowed string instruments. The wolf tone in violins and cellos was one of his earliest experiments. He investigated the acoustics of various violins and related instruments, as well as water splashes and Indian stringed instruments. "Experiments with mechanically-played violins" was one of his works. C V Raman Discovery behind the Blue colour of the sea- In 1919, Raman began investigating light scattering as part of his broadening foray into optics. His first amazing discovery was the mechanics of seawater's blue colour. In September 1921, he reflected on the Mediterranean Sea's blue colour while sailing home from England on the S.S. Narkunda. He tested the seawater with basic optical instruments, including a pocket-sized spectroscope and a Nicol prism. No.56 Lord Rayleigh's explanation in 1910, "The much-revered dark blue of the deep sea has little to do with the colour of water, but is the blue of the sky seen by refraction," was the strongest of many theories on the colour of the sea. C V Raman Inventions: Most photons are elastically dispersed as light is scattered from an atom or molecule. The incident photons have the same energy (frequency) as scattered photons, and therefore the same wavelength. Excitations of optical frequencies distinct from, and normally lower than, the frequency of the incident photons scatter a small fraction of scattered light (roughly one in ten million photons). Raman scattering may occur in gas when a molecule's vibrational, rotational, or electronic energy changes. "The character of scattered radiations allows us to obtain an insight into the ultimate structure of the scattering," Raman explained. Raman published his thesis on "Molecular Diffraction of Light" in 1922, the first of a series of investigations with his collaborators that eventually led to his discovery of the radiation effect that bears his name (on February 28, 1928). In 1928, C. V. Raman and K. S. Krishnan, as well as Grigory Landsberg and Leonid Mandelstam, independently identified the Raman effect. Raman's discovery was hailed by physicists as evidence of the quantum theory. The vibrational Raman effect is of primary interest to chemists. The Raman Effect was named a National Historic Chemical Landmark by the American Chemical Society in 1998, in recognition of its importance as a method for studying the structure of liquids, gases, and solids. The Raman Effect is distinct from the fluorescence mechanism. The incident light is completely absorbed in the latter case, and the system is transferred to an energetically excited state from which it can only transition to various lower states after a certain period (resonance lifetime). Both processes emit a photon with a different frequency than the incident photon, and the molecule is brought to a higher or lower energy level. However, the Raman Effect can occur for any frequency of incident light, which is a significant difference. The Raman Effect, in contrast to the fluorescence effect, is not a resonant effect.

Below we have given a long essay on CV Raman of 500 words is helpful for classes 7, 8, 9 and 10 and Competitive Exam Aspirants. This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.

Born at Trichinopoly in Tamil Nadu on 7th November, 1888, his father was a lecturer in Mathematics and Physics, in Mrs AV Narasimha Rao College, Visakhapatnam, and later joined Presidency College, Madras. His maternal grandfather was a Sanskrit scholar, well versed in ‘navya nyaya’ or modern logic.

So, from an early age, he was immersed in an academic atmosphere. He was a diligent student. He entered the Presidency College, Madras, in 1902, and in 1904 passed his BA examination, winning the first place and a gold medal in Physics. In 1907, he gained his MA degree, obtaining the highest distinctions. His earliest researches in optics and acoustics—the two fields of investigation to which he dedicated his entire career were carried out while he was a student. Since at that time a scientific career did not appear to offer the best possibilities, Raman joined the Indian Finance Department in 1907. Though the duties of his office took most of his time, Raman found opportunities for carrying on experimental researches in the laboratory of the Indian Association for the Cultivation of Sciences at Calcutta.

In 1917, he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. Raman’s main research was focussed on acoustics and musical instruments, and led to his election as fellow of the Royal Society in 1924. It was during a trip to England in 1921 that he was fascinated by the blue colour of the Mediterranean.

With a very simple experiment, he convinced himself that the blue colour of the sea was not only due to the reflection of the sky, as proposed by Lord Rayleigh, but mainly due to the scattering of light by water molecules. On his return to Calcutta, he began a systematic study of the scattering of light by different liquids, culminating in the discovery of a totally new kind of radiation, predicted by the quantum theory and named after him.

There Raman radiations carry vital information about the internal structure of the scattering molecules, and have proved to be of immense importance in studying molecular structures. His efforts finally paid off when he was awarded the Nobel Prize in Physics in 1930, the first to be ever won by an Indian. Thereafter, he became the Honorary Secretary of the Indian Association for the Cultivation of Sciences. After 15 years in Calcutta, he became Professor at the Indian Institute of Science at Bangalore (1933-1948) and in 1948, he became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he was the Editor.

Raman sponsored the establishment of the Indian Academy of Sciences and served as its President since its inception. He was also the President of the Current Science Association, Bangalore, which publishes Current Science. (India)

Raman has done credible work in his field and his early memoirs appeared as Bulletins of the Indian Association for the Cultivation of Sciences. These dealt with the maintenance of vibrations and the theory of musical instruments of the violin family. In 1922, he published his work on the ‘Molecular Diffraction of Light’, the first of a series of investigations with his collaborators which ultimately led to the discovery, on 28th February, 1928, of the radiation effect, which is named after him. This work bagged him the 1930 Nobel Prize in Physics.

Some other investigations which propelled the world of science during his time were the experimental and the theoretical studies on the diffraction of light by acoustic waves of Ultrasonic and Hypersonic frequencies. In 1932, he and Suri Bhagavantam discovered quantum photon spin. During his term at IISc, he admitted the talented electrical engineering student, GN Ramachandran, who went on to become a recognised X-ray crystallographer.

Short Essay on CV Raman 200 Words in English

Below we have given a short essay on CV Raman is for Classes 1, 2, 3, 4, 5 and 6. This short essay on the topic is suitable for students of class 6 and below.

In 1948, Raman, through studying the spectroscopic behaviour of crystals, approached fundamental problems of crystal dynamics in a new manner. His laboratory has been dealing with the structures and properties of diamond, the structure of optical behaviour of numerous iridescent substances like opal and pearls.

This luminous star in the firmament of the scientific fraternity has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected as a fellow of the Royal Society in 1924 and knighted in 1929. In 1941, he was awarded the Franklin Medal. In 1954, he was conferred upon, the Bharat Ratna. He got the Lenin Peace Prize in 1957.

Another big honour was that the American Chemical Society and IACS recognised his discovery as an International Historic Chemical Landmark. India celebrates National Science Day every year on 28th February to remember the discovery of Raman effect that took place in 1928.

At the end of October, 1970, he collapsed in his laboratory. Doctors gave him four hours to live. He survived and asked to be shifted from the hospital to the gardens of his institute. He passed away on 21 st November, 1970. His life was a testimony to hard work, patience and perseverance for achieving one’s goals. One should also be level headed and not go overboard on attaining success. With him, dawned an era of high quality science, and he showed the light for others to follow.
