Short Background: Raman Effect & Why We Celebrate
National Science Day exists because of one historic Indian discovery.
- On 28 February 1928, C. V. Raman experimentally showed that when light passes through a transparent medium, its wavelength can change due to scattering – the phenomenon now called the Raman Effect.
- This discovery revolutionised spectroscopy, and Raman received the Nobel Prize in Physics in 1930, the first Asian to do so in the sciences.
- The NCSTC proposed in 1986 that 28 February be celebrated annually as National Science Day to honour the Raman Effect and promote scientific temper.
Today, schools, colleges, coaching centres and research labs observe the day with science exhibitions, model demonstrations, quiz competitions, poster‑making, speeches and essay contests.
