National Science Day 2020
NEW DELHI [Maha Media]: Each year, the government celebrates National Science Day on February 28 to commemorate the announcement of the discovery of the ‘Raman Effect’ by Sir CV Raman. The day was designated as National Science Day in 1986. Sir Chandrasekhara Venkata Raman was awarded the Nobel Prize in Physics 1930 for the discovery. The theme of National Science Day 2020 is ‘Women in Science’.
Raman Effect is the change in the wavelength of light that occurs when it is deflected by molecules. A light beam traversing through a transparent sample of a chemical compound sees a small fraction of the light emerging in a different direction to that of the incoming beam.A small part of that light has a differing wavelength from the incident light. This is because of the Raman Effect. The discovery of Raman Effect gave proof of the quantum nature of light. KS Krishnan co-worked with Raman during the experiment. While Krishnan did not share the Nobel Prize with Raman, he was mentioned prominently in the Nobel lecture the laureate delivered.
Several institutions organise open house for laboratories and teach students about career opportunities available in a particular research institution.The National Council for Science and Technology Communication (NCSTC), Department of Science and Technology (DST), acts as a nodal agency to support and coordinate celebration of the National Science Day.
