National Science Day is celebrated on 28 February each year to mark the discovery of the Raman Effect by Sr. CV Raman. He was given the Nobel Prize in Physics in 1930 for his research on The Raman Effect. This day highlights the importance of science and its significance in our day-to-day life. The National Council for Science and Technology Communication (NCSTC) popularises science in India. And so, in 1928, it was the NCSTC who proposed the idea of rewarding 28 February as the National Science Day Celebration.
About Sir. CV Raman
Chandrasekhara Venkata Raman was born an extraordinarily intelligent child. He matured at an unusually early age. He completed his bachelor’s degree with honors in physics just at the age of 16. And published his first paper based on the diffraction of light while he was still graduating. He has won many medals and has achieved a lot of recognition. Some of his prestigious awards include:
| Awards | Which Year | Why |
| Curzon Research Award in 1912 | 1912 | He received this award while working in the Indian Finance service. This award was given during Lord Curzon’s rule |
| Knight Bachelor Award in 1930 | 1930 | His involvement in the 1929 Birthdays Honors was delayed. So, as an approval Lord Erwin conferred him with this award in the Rashtrapati Bhawan. |
| Nobel Prize in Physics | 1930 | For his research on the scattering of light and the discovery of the Raman effect. |
| The Bharat Ratna Award | 1954 | He received the highest Civilian Award. |
| Lenin Peace Prize | 1957 | This award was given to the prominent supporters or Communists of the Soviet Union. |
His most popular discovery was the Raman effect.
About The Raman Effect
The Raman Effect is the scattering of light particles by molecules of a medium. Let us understand this with an example. Why does the ocean appear blue despite the water being colourless? It’s due to the Raman effect. The sunlight consists of 7 colours – Violet, Indigo, Blue, Green, Yellow, Orange, and Red (VIBGYOR). The ocean water is able to absorb green, yellow, orange, and red colours. But it scatters violet, indigo and blue. So the colourless water in the ocean appears to be blue. This phenomenon is the Raman effect.
