CV Raman Death Anniversary 2025: Date and Interesting Facts About the Nobel Prize-Winning Indian Scientist

Sir Chandrasekhara Venkata (CV) Raman was an Indian physicist known for his work in the field of light scattering. CV Raman is popularly known for the discovery of the Raman Effect, which explains how light changes its wavelength when passing through a transparent material. The death anniversary of Sir Chandrasekhara Venkata Raman is observed every year on November 21 to honour one of India’s greatest scientists and Nobel laureates. This day serves as a reminder of his exceptional contributions to physics, especially his groundbreaking discovery of the Raman Effect, which revolutionised the scientific understanding of light scattering. Everything You Must Know About the Indian Physicist Sir CV Raman.

Using a spectrograph that he developed, he and his student K. S. Krishnan discovered that when light traverses a transparent material, the deflected light changes its wavelength. This phenomenon, a hitherto unknown type of scattering of light, which they called modified scattering, was subsequently termed the Raman effect or Raman scattering. In this article, let’s know about some interesting facts about the Nobel prize-winning Indian scientist.

Interesting Facts About CV Raman - the Nobel Prize-Winning Indian Scientist

1. CV Raman was the first Asian and first non-white scientist to win the Nobel Prize in Physics in 1930.
2. After the independence of India, CV Raman was selected as the first national professor of India.
3. He played a key role in establishing the Indian Academy of Sciences and contributed significantly to the growth of the Indian Institute of Science (IISc), Bengaluru.
4. The discovery of the Raman Effect, which explains how light changes its wavelength when passing through a transparent material.
5. In 1930, Raman received the Nobel Prize in Physics for this discovery and was the first Asian and non-White person to receive a Nobel Prize in Physics.
6. Raman also conducted pioneering research in the acoustics of musical instruments, especially the mridangam and tabla. He studied these musical instruments to explore how sound and vibration create rhythm and tone.
7. Raman founded and edited key scientific journals such as the Indian Journal of Physics and the Proceedings of the Indian Academy of Sciences.

CV Raman’s work laid the foundation for modern spectroscopy and put India on the global scientific map. The day encourages students, researchers, and science enthusiasts to appreciate the importance of scientific inquiry, innovation, and dedication to knowledge. On this day, schools and institutions use this day to organise science talks, exhibitions, and discussions on Raman's contributions.
