India celebrates National Science Day on February 28 every year to mark the discovery of Raman Effect by Sir C V Raman. Sir Raman discovered the Raman Effect on Feb 28, 1928.

Wikipedia says Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is an exchange of energy and a change in the light’s direction. Typically this involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy.

The theme of the National Science Day for the year 2018 was “Science and Technology for a sustainable future.” This year, the day was celebrated under the “Women in Science.”

National Science Day – History

The National Science Day was designated in the year 1986 and was celebrated for the first time in the year 1987.
