Explained | National Science Day 2023 : The Raman Effect I Drishti IAS 

In 1986, the Government of India, under then Prime Minister Rajiv Gandhi, designated February 28 as National Science Day to commemorate the announcement of the discovery of the “Raman Effect”. This year’s edition is being celebrated under the theme of “Global Science for Global Wellbeing”, in light of India’s G20 presidency.
The Raman Effect was the discovery which won physicist Sir CV Raman his Nobel Prize in 1930.
Conducting a deceptively simple experiment, Raman discovered that when a stream of light passes through a liquid, a fraction of the light scattered by the liquid is of a different colour.
