Raman Effect Current Affairs - 2020
Every year on February 28, India celebrates National Science Day to mark the discovery of Raman Effect by Sir C V Raman. Raman Effect was discovered by the professor on February 28, 1928. This year, the National Science Day is celebrated under the theme
Theme: Women in Science
The National Science Day was first designated in 1986 and was first celebrated in 1987. Sir C V Raman announced his discovery on this day. He was later awarded the Nobel Prize for this discovery in 1930.
It was the National Council for Science and Technology that asked the GoI to pronounce February 28 as the National Science Day. The Council operates under Department of Science and Technology and is the nodal agency in implementing the celebrations of the day.
The Effect states about scattering of light. When a beam of light comes out of a liquid, the light wave scattered in a direction is different from that of the incoming light wave.

The Union Human Resource Minister Prakash Javadekar launched the STARS scheme on National Science Day (28th February).
- STARS is an acronym for Scheme for Translational and Advanced Research in Science to fund Science projects.
- The scheme will be implemented at the cost of Rs 250 crores.
- Under the scheme 500 science projects will be funded whose selection will be made based on competition.
- IISC will be the coordinator of the scheme.
National Science Day: 28th February
The National Science Day is celebrated on 28th February every year in the memory of Indian physicist and a Nobel laureate Sir C.V. Raman. The National Day of Science is celebrated on 28th February to commemorate the discovery of Raman Effect for which he was awarded Nobel Prize in the year 1930. The theme of the 2019 National Science Day is Science for people and people for science.
Raman Effect refers to the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels. Part of the light beam after passing through transparent medium gets scattered and the wavelength of these scattered rays is different from that of the incident rays of light. This phenomenon of scattering of light is termed as Raman Scattering and the cause of scattering is called the Raman Effect.
