Sir Chandrasekhara Venkata Raman was a Tamil Brahman who had worked from 1907 to 1933 at the Indian Association for the Cultivation of Science, Kolkata, West Bengal. Here, he had researched various topics of physics of which one is the Raman Effect, which marked the greatest discovery in the field of science in Indian History.
In 1986, the National Council for Science and Technology Communication (NCSTC)asked the Government of India to designate 28 February as National Science Day. The government had accepted it and declared 28 February as National Science Day in 1986. The first National Science Day was celebrated on February 28, 1987.

It is not easy to say the way science and new technologies are evolving. With the help of science, human have made their lives better and easy. Not only this, we have made impossible things possible like man is reaching into space, robots, computers etc. have been invented.
Therefore, science holds great importance in our lives. India has also contributed a lot in the field of science. Many great scientists were born in India and recognized India in the field of science and made a separate place too. On 28th of February every year the National Science Day is celebrated in India. Let us study through this article, why and how National Science Day is celebrated in India, what is the theme of 2019 etc.

In 1928 an Indian Scientist Sir Chandrasekhara Venkata Raman discovered a phenomenon known as Raman Effect and for his remarkable discovery in 1930 he got Nobel Prize, which was the first Nobel Prize in India in the field of Science and to mark this discovery every year National Science Day is celebrated.

What is Raman Effect
Source: www.aboutforensics.co.uk.com
It is a phenomenon in which change in the wavelength of light occurs when a beam of light is deflected by molecules. When a beam of light travels from a dust free transparent sample of a chemical compound, then a small fraction of the light emerges in the direction other than that of the incident light. Most of the scattered light wavelength is unchanged and in small part if the wavelength is different from that of incident light it is due to Raman Effect.
Awards which were won by CV Raman are: Fellow of the Royal Society (1924), Knight Bachelor (1929), Nobel Prize in Physics (1930), Bharat Ratna (1954), Lenin Peace Prize (1957) and Fellow of the Royal Society (1924).
