Brief Introduction to Sir C.V. Raman

Sir Chandrasekhara Venkata Raman was born in Tiruchirappalli in the year November 7, 1888. He is one of the physicists worked on light scattering phenomenon and discovered the Raman Effect. He was the first Indian to receive the Nobel Prize in Physics in the year 1930 for his work on scattering of light. Besides Nobel Prize, he also received many awards, including Bharat Ratna. His last breath is on 21 November 1970.

What is Raman Effect?

The Raman effect is a change in the length of a light wave that happens when molecules move a light beam. Whenever a beam of light goes through a clear, dust-free sample of a substance, a small amount of light comes out in a different direction than the incident beam.

What's the Importance of the Raman Effect:

The Raman effect helps explain many natural things, like why the sky is blue, why the sun rises early and sets late, and so on. It also tells us why the sky looks red at sunrise and sunset.

National Science Day is a tribute to the work of Sir C.V. Raman and for his discovery of Raman Effect. It is celebrated so high as he is the first Indian physicist to receive the Nobel Prize, and it is important to remember people like him and their efforts.
