CV Raman Birthday 2022: History, Significance and Celebrations

Sri Chandrasekhara Venkata Raman popularly known as Sir CV Raman was one of the greatest Indisn physicists to ever existed, he is known for his work in the field of scattering. 

Sir CV Raman was born on 7th Novenher and that’s why his birth anniversary is annually celebrated on 7th November in India during which tribute is paid to him for all of his contributions and achievements throughout his life. 

He is most popularly known for his discovery of Raman effect and he is seen as an inspiration for all the science-enthusiasts of the nation. His discovery of Raman effect is also celebrated as National Science Day in India annually on 28th February.

CV Raman Birthday History: 

Dr. C.V. Raman was born on 7th November, 1888 in a South Indian Brahmin family in Tiruchirappalli, Tamil Nadu. His father’s name was Chandrasekhara Ramanathan Iyer who was a lecturer in Mathematics and Physics in a college in Vishakhapatnam. His mother’s name was Parvathi Ammal. He was an intelligent and brilliant student since his early childhood. At the age of 11, he passed his matriculation and 12th class at the age of 13 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 done his Master’s in Physics from the same college. 

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 Assistant Accountant General. 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 the Professor at the Indian Institute of Science at Bangalore from 1933-1948 and since 1948, he became the Director of the Raman Institute of Research at Bangalore which was established and endowed by him only. 

Later 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). Other researches carried out by Dr. C.V. Raman were: Diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies and 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. As briefly described that 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. 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. 

CV Raman Birthday Significance: 

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 really 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 in the country. 

Today CV Raman is known worldwide for his discovery of Raman effect. Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is both an exchange of energy and a change in the light’s direction. Typically this effect involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy. This is called normal Stokes Raman scattering. The effect is exploited by chemists and physicists to gain information about materials for a variety of purposes by performing various forms of Raman spectroscopy.

He made another great discovery which was the discovery of the physics of light behind the blue colour of seawater. During a voyage home from England on board the S.S. Narkunda in September 1921, he contemplated the blue colour of the Mediterranean Sea. Using simple optical equipment, a pocket-sized spectroscope and a Nicol prism in hand, he studied the seawater. Raman could view the water using Nicol prism to avoid the influence of sunlight reflected by the surface. He described how the sea appears even more blue than usual, contradicting the earlier popular belief presented by Rayleigh. 

Dr. C. V. Raman was the greatest scientist of modern India and one of the greatest intellects the country has produced in its long history. His life’s work consisted in throwing light upon the nature of lights, and the world honoured him in many ways for the new knowledge which he won for science. And that’s why CV Raman has left a huge legacy behind him not just in India but in the field of science worldwide and that’s why he is honoured and celebrated on his birth anniversary. In India, he is a source of inspiration for many students especially for those who are in the field of science.

CV Raman Birthday Celebrations: 

On the occasion of CV Raman birth anniversary tribute is offered to him at various public institutions across the country especially in educational institutions across the country like schools and colleges. In many schools and colleges speeches, debates or activities presenting theories of CV Raman are carried out on this day this inspiring and encouraging the students towards him. 

At various places in the country conferences, public speeches, tributary events by politicians also takes place on this occasion. Overall it is a day in which tribute is offered to CV Raman and often it is done by putting s garland around the neck of many statues of CV Raman across the country. Sometimes science exhibitions are also held on this Day at few locations to encourage the people to take interest towards science and technology. 

Many people also likes to pay a visit to many libraries and museums across the country dedicated to Sir CV Raman. Students use this opportunity to learn more from the biography of CV Raman to get inspite from him and adopt some of his qualities in their life to make it more worthy and useful for the society. Some science enthusiasts also celebrate this day by cutting cake in the honour of Sir CV Raman. 

Most Searched FAQs on CV Raman Birthday: 

1. When is CV Raman birth anniversary celebrated? 

CV Raman birth anniversary is annually celebrated on 7th November in India. 

2. What is special about CV Raman? 

CV 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. 

3. Why is the sky blue according to CV Raman? 

The smallest wavelengths scatter more easily and these are in the blue spectrum. This is why the sky and the sea appear blue.
