National Science Day 2022 – History, Theme, and Significance
New Delhi: Chandrasekhara Venkata (CV) Raman, an Indian physicist, made a key discovery in the science of spectroscopy on this day in 1928, which was eventually named after him – the Raman Effect. CV Raman was given the coveted Nobel Prize in Physics in 1930 for his efforts.
The Raman Effect
The Raman Effect, which describes the change in wavelength of light that happens when a light beam is deflected by molecules, was discovered on February 28, which is observed as National Science Day.
Every year on February 28th, National Science Day is observed to honour Indian physicist CV Raman’s discovery of the “Raman Effect.” The events this year will focus on an ‘Integrated Approach in Science and Technology for a Sustainable Future.’
The National Council for Science and Technology Communication (NCSTC) approached the Center in 1986 and suggested February 28 to be designated as National Science Day.
The inaugural commemoration of the day took place on February 28, 1987. The Raman Effect was discovered on this day by scientist Chandrasekhara Venkata Raman. In 1930, Raman was awarded the Nobel Prize for the scattering of light and the discovery of the Raman effect.
History
When CV Raman was working at the Laboratory of the Indian Association for the cultivation of science in Kolkata, he discovered the Raman effect. He first discovered the phenomenon in 1921, when he noted the Mediterranean Sea’s blue colour and icebergs. He conducted several tests and was the first to publish his findings in 1928.
Theme
The theme of National Science Day 2022 is Integrated Approach in Science and Technology for a Sustainable Future to promote public knowledge about the value of science.
Public speeches, radio, television, scientific movies, science exhibitions on topics and concepts, debates, quiz contests, lectures, and science model displays are all ways that educational institutions commemorate National Science Day.
Significance
When a light beam is deflected by molecules, the Raman Effect describes how the wavelength of light changes. The day honours C V Raman, a legendary Indian scientist and encourages India’s youth to follow his steps.
