National Science Day is celebrated in India on 28 February in memory of which event?

  1. A.The discovery of the neutron
  2. B.The announcement of the Raman Effect
  3. C.The discovery of penicillin
  4. D.The launch of the satellite Aryabhata

Correct answer

B. The announcement of the Raman Effect

Explanation

The correct answer is B, the announcement of the Raman Effect. C. V. Raman announced his discovery of the scattering of light that carries his name on 28 February 1928, and he was awarded the Nobel Prize in Physics for it in 1930. The Government of India designated the date as National Science Day in 1986 and the first observance was held in 1987.

Option A, the discovery of the neutron by James Chadwick, also belongs to the early 1930s but has no connection with any Indian observance. Option C, the discovery of penicillin by Alexander Fleming, is a landmark in medicine and is placed here only as a plausible science event. Option D, the launch of Aryabhata, India's first satellite, took place in 1975 and is associated with the Indian space programme rather than with Science Day. Hold the three elements together: Raman, 1928 and 28 February.
