India observes National Science Day on February 28th each year to commemorate Indian physicist C.V. Raman's 1928 discovery of the "Raman Effect," or the phenomenon of light scattering.
In 1930, Chandrasekhar Venkat Raman was awarded the Nobel Prize in Physics for his pioneering discovery of photon scattering, which was subsequently dubbed the "Raman Effect." Various educational, scientific, and research institutes host quizzes, seminars, and other events on National Science Day to honour this accomplishment.
The Raman Effect: What Is It?
The website of the Ministry of Culture describes the Raman Effect as the phenomenon of photon scattering by excited atoms at high energies, which is an event in spectroscopy. Put simply, it's a shift in light's wavelength that happens when light beams travel through clear materials free of dust particles.
A tiny portion of the light, aside from the transmitted (coming) rays, is scattered in different directions when light rays travel through a transparent material free of dust. Most of this scattered light is still at the same wavelength. But a tiny percentage experiences a wavelength shift, giving rise to the Raman Effect.

History of National Science Day: To acknowledge the value of science and technology in government relations with India, the National Council for Science and Technology Communication (NCSTC) proposed in 1986 to observe National Science Day on February 28. The proposal was approved by the government, and on February 28, 1987, the inaugural National Science Day was observed.

Why Do We Celebrate National Science Day?
The government says the goal is to raise public awareness of the value of scientific applications in everyday life, honour scientific accomplishments, have conversations about a range of topics, and give scientists a chance to experiment with new technologies for scientific advancement. It seeks to popularise science and technology in the nation and inspire people with a scientific worldview.
