C. V. Raman won the 1930 Nobel Prize in Physics for his work on light scattering and the discovery of the Raman Effect. The discovery, announced on 28 February 1928, is commemorated in India each year on National Science Day. The phrase “Nobel predictions” does not identify a documented prediction about Raman in the sources available here; his well-established story is one of scientific curiosity pursued alongside government service.
Who was C. V. Raman?
Chandrasekhara Venkata Raman was born in Tiruchirappalli, southern India, on 7 November 1888. His father taught mathematics and physics, and Raman entered Presidency College in Madras in 1902. He earned a BA in 1904 and an MA in 1907, developing early interests in optics and acoustics along the way. Nobel Prize Outreach’s biography of Raman recounts these early years.

How Raman pursued research alongside government service
In 1907, Raman joined India’s Finance Department. Rather than abandon physics, he sought opportunities to conduct experiments at the Indian Association for the Cultivation of Science (IACS) in Calcutta, now Kolkata. In 1917, he left government service to take the Palit Professorship in Physics at the University of Calcutta, while continuing his research at IACS. His path shows how he sustained scientific work before taking up a full-time academic post.
What is the Raman Effect?
When light passes through a transparent material, molecules scatter it. Most of the scattered light retains the wavelength of the incoming beam. A small fraction, however, emerges at different wavelengths after interacting with the molecules. That wavelength shift is the Raman Effect, as explained by the Government of India’s Press Information Bureau overview of National Science Day.
#1 Best Overall
The shift makes Raman spectroscopy useful: scientists can investigate materials by studying the light scattered from them. President Ram Nath Kovind’s 2020 National Science Day address described Raman spectroscopy as a powerful tool for scientific investigations and industrial applications. The key distinction is that the effect concerns a small portion of scattered light, not every ray that is scattered.
What did C. V. Raman win the Nobel Prize for?
Raman received the Nobel Prize in Physics in 1930 for his work on the scattering of light and discovery of the effect named after him. The discovery announcement is dated 28 February 1928 in Kovind’s 2020 address; the award followed two years later, as recorded by Nobel Prize Outreach.

Was C. V. Raman the first Indian to win a Nobel Prize?
Not if “Nobel Prize” means any category. Rabindranath Tagore received the Nobel Prize in Literature in 1913, before Raman’s Physics award. A more precise distinction is that Raman was the first Asian to receive a Nobel Prize in science, a description attributed to President Ram Nath Kovind in his 2020 address. The CBSE educational resource also notes Tagore’s earlier Nobel recognition.

Why is National Science Day celebrated on 28 February?
India observes National Science Day on 28 February to commemorate Raman’s discovery of the light-scattering phenomenon. According to the Press Information Bureau’s 2024 explainer, the designation was requested in 1986 and the first National Science Day was held on 28 February 1987. The annual observance connects a foundational scientific discovery with public attention to science and its applications.

Raman’s lasting legacy
Raman’s legacy has two closely linked dimensions: a scientific method of investigating matter through scattered light, and a public commemoration that brings his discovery into India’s annual science calendar. In a quotation attributed to Raman speaking to young graduates in 1969, as reproduced in Kovind’s 2020 address, he said: “We need a spirit of victory, a spirit that will carry us to our rightful place under the sun, a spirit which can recognize that we, as inheritors of a proud civilization, are entitled to our rightful place on this planet. If that indomitable spirit were to arise nothing can hold us from achieving our rightful destiny.”
