National Science Day is celebrated in India on February 28th every year. This day marks the discovery of the Raman Effect by Indian physicist Sir C.V. Raman on February 28, 1928. The Raman Effect refers to the phenomenon of scattering of light when it passes through different materials, leading to changes in its wavelength. This discovery earned Sir C.V. Raman the Nobel Prize in Physics in 1930, making him the first Asian to receive this prestigious award in the field of science.

National Science Day aims to spread awareness about the importance of science and its applications in our daily lives. It also commemorates the contributions of Indian scientists to the advancement of science and technology. On this day, at ACET various events such as science exhibitions, seminars, lectures, and competitions are organised to encourage scientific temper among people, especially students. The theme for National Science Day may vary each year, focusing on different aspects of science and technology.
