Sir C V Raman and ‘Raman Effect’
Scientists over the world contribute to science by their discoveries and inventions one such great scientist was Sir Chandrasekhara Venkata Raman.
Sir C V Raman was an Indian Physicist born on 7th November 1888 in Tiruchirapalli, Madras.
During the times he was working in ‘Laboratory of Indian Association for the Cultivation of Science, Kolkata’ He discovered that when a beam of light enters a medium, light got scattered, a fraction of scattered light is of wavelength (colour) different than that of entered light. It is known as ‘Raman Effect’.
In other words we can say that change in wavelength of a fraction of light scattered by molecules of a medium is called ‘Raman Effect’.
Sir CV Raman discovered it on 28th February 1928 and got the Nobel Prize for it in 1930.
This was the first Nobel prize for India in the field of science.
Why NSD is Observed
After a demand from ‘ National Council for Science and Technology Communication (NCSTC), to commemorate the discovery of ‘Raman Effect’ Government of India in 1986 designated 28th February as ‘National Science Day’.
First ‘National Science Day’ was observed on 28th February 1987.
This day is to raise the awareness on the Importance of science.
On this day science exhibitions, quiz competitions, debates and many such activities are organized in educational institutions.
Theme of year 2023 is “Global Science for Global Wellbeing”
