National Science Day 2026 – Raman Effect, Theme, Facts and MCQs
Raman Effect, C. V. Raman, the 2026 focal theme and high-value science GK for competitive exams.
Fact-checked: 19 July 2026
Introduction and Background
National Science Day is celebrated in India on 28 February to commemorate Sir C. V. Raman’s discovery of the Raman Effect on 28 February 1928. The observance promotes scientific temper, public engagement with science and awareness of India’s scientific achievements.
The Raman Effect concerns the change in wavelength of light when a beam is scattered by molecules. The discovery became an important tool for studying molecular structure. C. V. Raman received the Nobel Prize in Physics in 1930, becoming the first Asian to receive a Nobel Prize in a branch of science.
The National Council for Science and Technology Communication proposed the observance, and the first National Science Day was celebrated in 1987. Exam questions commonly connect the date with Raman, spectroscopy, the Nobel Prize, the Indian Association for the Cultivation of Science and the annual focal theme.
Exam strategy: First learn the date and central personality or institution. Next connect the day with one constitutional article, treaty, organisation, headquarters, discovery or historical event. Finally, revise the “Do Not Confuse” box because examinations often place two similar observances in the same question. This method converts a simple date into a complete static-GK unit for APPSC, TSPSC, UPSC, SSC, Railway, Banking and Police examinations.
