New Delhi: National Science Day is being celebrated across the country today on 28 February. This day is celebrated to celebrate the work of Bharat Ratna and Nobel Prize winning scientist and physicist Chandrashekhar Venkatraman i.e. CV Raman.
The theme of Science Day this year is ‘Empowering Indian Youth for Global Leadership in Science and Innovation for Developed India’.
On this day, i.e. 28 February 1928, CV Raman announced the discovery of the Raman Effect. For this, he also received the Nobel Prize in the year 1930. In the year 1986, the Indian government decided to celebrate this day as Science Day.
The prize winning idea came while returning from a foreign trip
In the year 1921, CV Raman was working as a professor at the University of Calcutta. During this time, the university sent him to participate in the International Universities Congress to be held in London.
When he was returning by plane after staying in London for 15 days, he was very impressed by seeing the Mediterranean Sea spread far and wide in the sky. Raman discovered that the reason for water being blue is that water scatters the blue colour the most out of all the colours of light. This is also the reason for the sky being blue.
From here CV Raman started thinking about the scattering of light and started researching on it. He passed light through various objects and observed how light scatters when it passes through different objects. The result of this hard work was that he discovered the Raman Effect or Raman Scattering on 28 February 1928.
Use of Raman effect-
Became the first Asian to win the Nobel Prize
CV Raman was awarded the Nobel Prize in Physics in 1930. He was the first Asian to achieve this feat.
Raman’s name was nominated for the Nobel Prize by Lord Rutherford. This is the same Rutherford who is called the Father of Nuclear Physics. Rutherford’s experiments are often mentioned in NCERT books.
