National Science Day 2021: February 28 is observed as National Science Day in India as on this day, world-renowned scientist CV Raman invented the ‘Raman Effect’ in 1928.
This year, the theme for National Science Day is “Future of STI: Impacts on Education, Skills, and Work.
On the occasion of National Science Day 2021, here’s a look at Sir CV Raman’s contribution to Physics:
- Sir CV Raman received the Nobel Prize in 1930 for his work on the scattering of light and the discovery of the effect named after him ‘Raman Effect’.
- Being brought up under the aegis of his father a physics lecturer, CV Raman was well immersed in the subject since his childhood.
- CV Raman qualified class 10th at the age of 11 years and also attended school on a scholarship at the age of 13.
- Sir CV Raman started his experiments for studying how light is scattered; and thus came the Raman Spectroscopy for observing the vibrational, rotational, and other low-frequency modes in a system.
- In 1954 he received the highest civilian award from his home country, the Bharat Ratna.
- Dr Ernest Rutherford, the man who discovered the nucleus and the proton, referred to Raman’s spectroscopy in his presidential address to the Royal Society in 1929.
- Raman was also obsessed with working on the acoustics of musical instruments and was also the first to investigate the harmonic nature of the sounds of Indian drums.
- Sir CV Raman retired from the Indian Institute of Science in 1948 and established the Raman Research Institute in Bengaluru in 1949.
- He served there as its director and remained active there until his death on November 21, 1970.
