National Science Day 2025: National Science Day is observed on February 28 to honors the discovery of the Raman Effect by C.V. Raman. The objective of National Science Day is to raise awareness about science and inspire students, scientists, and researchers.
National Science Day 2025:
National Science Day is celebrated with great enthusiasm and pride in India on February 28 every year. This day is observed on February 28 to honour Sir CV Raman’s discovery of the Raman Effect in 1928 while working in the laboratory of the Indian Association for the Cultivation of Science, Kolkata.

The discovery, which earned him the Nobel Prize in Physics in 1930, marked a milestone in the field of science. On this day, the nation honors the contributions of scientists and encourages students to engage with the world of science and technology.

The discovery of the Raman Effect is considered a major achievement of India in the field of science. In memory of Raman’s discovery of the ‘Raman Effect’, the Government of India declared this day as National Science Day and celebrated this day for the first time in 1987.
National Science Day is celebrated in India on 28th February every year to commemorate the birth anniversary of Indian physicist Dr. C.V.

What is the Raman Effect
C.V. Raman discovered the Raman Effect on 28 February 1928. It describes the scattering of light when it passes through a transparent material and interacts with its molecules. Most of the light continues in the same direction, but a small portion is scattered with a change in energy, leading to variations in wavelength.
