National Science Day is widely known in India to mark the invention of the Raman effect by physicist C.V. Raman on February 28 in 1928. India has been celebrating National Science Day since 1986 when the Government of India determined to commemorate the announcement of the invention of the Raman Effect and to encourage the event of a scientific mindset within the nation.
National Science Day is noticed to advertise the importance of science in on a regular basis life and spotlight the varied actions, endeavours, and accomplishments within the scientific subject for the betterment of humanity.
Who was C.V. Raman?
Chandrasekhara Venkata Raman, popularly generally known as C.V. Raman, was born in Tiruchirapalli, Tamil Nadu in 1888. In 1921, as a professor on the University of Calcutta he was despatched as a delegate to the International Universities Congress in London. His journey again house nonetheless, is what modified his future.
On his 15-day return journey again house, whereas aboard the SS Narkunda, he was fascinated with the deep blue color of the Mediterranean sea. He discovered that the ocean seemed blue for just about the identical purpose the sky seems blue — the water was inflicting blue mild to scatter greater than different colors within the mild.

In the years that adopted, Raman turned engrossed with the ‘scattering question’. He started conducting many experiments to watch how mild behaved whereas it handed by various kinds of substances. His onerous work ultimately led him to the the invention of what’s now generally known as the Raman Effect, also called the Raman scattering on February 28, 1928. He was knighted in 1929, and in 1930, and turned the primary Asian to win a Nobel Prize for Physics.
What is the Raman effect?
Raman effect refers back to the inelastic scattering of sunshine by matter, leading to a shift within the frequency of the scattered mild. In easier phrases, it’s a change within the wavelength of sunshine that happens when a light-weight beam is deflected by molecules.
The Raman effect types the premise for Raman spectroscopy, which is utilized by chemists and physicists to achieve details about supplies. Spectroscopy is the examine of the interplay between matter and electromagnetic radiation.
The Raman Effect over time has been utilized in many fields comparable to chemistry, biology, drugs. The police too use a tool generally known as the Raman Scanner adopting this precept to search out out if persons are carrying any unlawful substances.
What is the target of National Science Day?
The primary goal of the commentary of National Science Day is to unfold the message of the significance of science and its utility among the many individuals. It is widely known as one of many essential science festivals in India yearly with the next targets:
-
To extensively unfold a message concerning the significance of scientific functions within the day by day lives of individuals.
-
To show all of the actions, efforts, and achievements within the subject of science for the welfare of human beings
-
To talk about all the problems and implement new applied sciences for the event of science
-
To encourage the individuals in addition to popularize science and expertise.
What is the theme of National Science Day 2025?
The theme for National Science Day 2025 is “Empowering Indian Youth for Global Leadership in Science & Innovation for Viksit Bharat.” It emphasizes the position of younger minds in driving India’s scientific and technological progress, aligning with the imaginative and prescient of Viksit Bharat 2047, which goals for a developed and self-reliant India.
