National Science Day: India Honours Nobel Laureate CV Raman

On February 28 every year India celebrates National Science day to pay homage to Chandrasekhara Venkata Raman. CV Raman was honoured with the Nobel Prize for Physics in 1930 for ‘Raman Effect’.

Wondering What Is The Raman Effect?

CV Raman was on a sea voyage when a question struck him ‘Why does the sea appear blue?’

And to that question, he discovered Raman Effect aka Raman scattering effect. According to Britannica the Raman Effect also known as the Raman Scattering Effect is the “change in the wavelength of light that occurs when a light beam is deflected by molecules”.

According to The Hans India, Raman discovered that colour of sea was blue because the sunlight is split into a spectrum of colours by molecules in the air and the only colour reflected by water that reaches our eyes is blue.

This groundbreaking discovery awarded CV Raman the Nobel Prize and he became the first Asian to be awarded the Nobel Prize in Physics.

This year the theme of the National Science Day is ” “Science for people and people for science.”
