National Science Day 2023: The Raman Effect, which CV Raman won the Nobel for
- India celebrates National Science Day every year on February 28th.
- In 1986, the Union Government, under then Prime Minister Rajiv Gandhi, designated February 28 as National Science Day.
- National Science Day is celebrated every year to commemorate the discovery of the “Raman Effect” by Sir C.V. Raman.
- Physicist Sir CV Raman won the Nobel Prize in 1930 for the discovery of the Raman Effect.
- The theme for National Science Day 2023 in light of India’s G20 presidency is “Global Science for Global Wellbeing”.
Sir C.V. Raman
- Birth: 7th November 1888 in Tiruchirapalli in modern Tamil Nadu.
- Education: The Presidency College at Chennai in 1902 aged just 13 for his graduation.
- He passed out in 1904 with a Gold Medal in Physics.
- Post-graduation: The University of Madras in 1907 with distinction.
- He continued to do research at the Indian Association for Cultivation of Sciences in Calcutta (IACS) and also published papers in leading international journals such as ‘Nature’ and ‘Physics Review’.
- It was at IACS that Raman along with his collaborators discovered what is now called the “Raman Effect”.
- This discovery on the scattering of light was made on February 28, 1928.
- This effect proved the quantum nature of light and had huge value at that time.
- The Raman Spectroscopy was based on this phenomenon.
- For this discovery, Raman was awarded the Nobel Prize in Physics in the year 1930. He became the first Indian, Asian and non-white person to win a Nobel Prize for the sciences.
- In 1933, he became the first Indian Director of the Indian Institute of Science (IISC) in Bangalore.
- He was the institute’s director till 1937 and the Head of the Physics Department till 1948.
- In 1948, he founded the Raman Research Institute (RRI) in Bangalore for conducting experiments in Physics. He continued to do research at RRI till his death in 1970.
