February 28: National Science Day
The National Science Day was celebrated at the Vigyan Bhawan on February 28, 2021. The programme celebrated under the focal theme- women in science.
About National Science Day
The national science day is celebrated on February 28 every year. The day is celebrated to mark the discovery of the ‘Raman Effect’. The national science day was designated by Government of India in the year 1986. Sir C.V. Raman had announced the discovery of the ‘Raman Effect’ on this day. He also received the Nobel Prize for this discovery in the year 1930. The celebration of the day is coordinated by the nodal agency National Council for Science & Technology Communication (NCSTC) under the Department of Science and Technology (DST).
Who received the awards?
The President of India conferred several awards for the science communication and popularization and to the women scientists on this occasion. Some of the awards include:
- National Science and Technology and Communication Awards
- SERB Women Excellence Awards
- Augmenting Writing Skills for Articulating Research (AWSAR) awards and
- National Award for Young Woman Showing Excellence Through Application of Technology for Societal Benefits.
About Raman Effect
Raman effect is inelastic scattering of the photons by matter where there is an exchange of energy and change in the direction of light. This effect comprises the vibrational energy which is gained by the molecule when the incident photons from visible laser are shifted to the lower energy. This effect takes place when light enters in the molecule and interacts with the electron density of chemical bond. This causes the electromagnetic field in molecule which in turn leads to vibrational and deformation of the frequency shift.
