National Science Day

National Science Day is celebrated every year on February 28. National Science Day is celebrated to commemorate discovery of the ‘Raman Effect’, which led to Indian scientist Sir Chandrasekhara Venkata Raman or CV Raman winning the Noble Prize in Physics in 1930. In simple terms, Raman Effect is the change in wavelength of light when a beam is deflected by molecules, in the laboratory of the Indian Association for the Cultivation of Science, Kolkata.

What is Raman Effect?

In simple terms, the Raman Effect states that when a wave of light comes out of a liquid, some part of this light wave is scattered in a direction that is different from the direction of the incoming light wave. His research shows why the color of seawater looks blue. Raman Effect is about the flexible distribution of photon particles.
