National Science Day is observed in India every year on which date?
- A.28 February
- B.11 May
- C.22 December
- D.15 September
Show answer
Correct answer: A. 28 February
Explanation
The correct answer is A, 28 February. On this day in 1928 C. V. Raman announced the discovery of the Raman Effect, the scattering of light with a changed wavelength when it passes through a transparent medium, and the discovery brought him the Nobel Prize in Physics in 1930. The day has been kept every year since 1987 on a fresh theme decided by the Government. Option B is wrong because 11 May is National Technology Day, kept for the Pokhran-II tests of 1998. Option C is wrong because 22 December is National Mathematics Day, the birth anniversary of Srinivasa Ramanujan. Option D is wrong because 15 September is Engineers' Day, the birth anniversary of Sir M. Visvesvaraya. Papers put all four national days in one question, so read which field is named before choosing.
