NSD or National Science Day is celebrated on 28th February to commemorate the discovery of the 'Raman effect' for which Sir C.V. Raman won the Nobel Prize.
The National Science Day celebrations consist of public speaking, science films, science exhibitions, science-related events, and many other activities across India. In addition, the Government of India recognizes and congratulates scientists who have made significant contributions in the field of science.
In 1986, the National Council for Science, Technology, and Communications (NCSTC), requested the central government to declare 28th February as the national science day date. This is not only to commemorate Sir C.V. Raman's achievements but also to recognize the achievements in the scientific field by other scientists.
After the first National Science Day on 28th February 1987, the NCSTC announced the creation of the National Science Promotion Award, which recognizes individuals for their contributions to science and communication.
NSD is celebrated by spreading the importance and improvement of science in the daily lives of the general public. This celebration also has the following goals in mind:
Many National Awards are conferred to prestigious scientists who made a difference in the field and who dedicated uncompromised time and effort in science:

Q.2. When was 28th February declared National Science Day?
The NCSTC requested the Government of India to celebrate 28th February as National Science Day. India accepted and declared National Science Day in 1986. The first National Science Day was celebrated on 28th February 1987.
Q.3. Who was C.V. Raman, and what is the Raman effect?
Dr Chandrasekhar Venkata Raman was a well-known scientist and physicist with bachelor's and master's degrees from Presidency College in Madras. In addition to his government activities, he participated in many science contests and received a grant from the Government of India.
While working in the laboratory of the Indian Science and Cultivation Association of Kolkata in 1928, he discovered a spectroscopic phenomenon which is now known as the Raman effect. He won the Nobel Prize for this amazing discovery in 1930. This was the first Indian Nobel Prize in the field of science.
The Raman effect is the change in the wavelength of light that occurs when a light beam is deflected due to a molecule. When a beam of light passes through a clear, dust-free compound sample, a small portion of the light, with different wavelengths, exits in a different direction than the incident beam. Its existence is the byproduct of the Raman effect.
