C.V. Raman death anniversary: India loses its finest scientist and Nobel prize winner today

On November 21, 1970, India lost one of the most brilliant minds, Sir Chandrasekhara Venkata Raman, popularly known as C.V. Raman. He was a physicist and had exceptional talent; his groundbreaking discovery of the Raman effect in 1928 revolutionized the field of spectroscopy and got him the Nobel Prize in 1930. Sir C.V. Raman was the first non-white human to win this prestigious award.

Early life and contributions

Sir C.V. Raman was born on November 7, 1888, in Tiruchirapalli. He showed a great interest in science from a very young age. Further, he graduated from the Presidency College in Madras with a Master’s degree in Physics in 1907. At the age of 18, he published his first scientific paper on "unsymmetrical diffraction bands due to a rectangular aperture" in the British journal in 1906, and he published his second paper in 1907 on the surface tension of liquids.

C.V. Raman cleared the entrance exam for the Indian Finance Service with the first position in February 1907 and was posted in Kolkata as Assistant Account General in June 1907. After a brief stint as an accountant, he joined the Indian Association for the Cultivation of Science in 1917, where he started his illustrious career.

Discovery of the Raman Effect

The most significant contribution of C.V. Raman was the discovery of the Raman Effect, which is a phenomenon that occurs when light interacts with molecules. According to this, when a beam of light strikes a molecule, a small fraction of the scattered light shows a change in its wavelength.

This change in wavelength is known as the Raman effect. It provides you with important information related to the vibrational and rotational energies of the molecules, allowing researchers and scientists to identify and characterize different materials.

The Legacy and Recognition

The discovery of the Raman effect had a profound impact on various fields, not only in physics but also in chemistry, biology, and material science. Moreover, his work led to the development of Raman spectroscopy, a tool for analyzing the composition and structure of materials. For his contribution, he was awarded the Nobel Prize in 1930, knighted by the British government in 1929, and became a member of the Royal Society in 1924.

In 1948, C.V. Raman established the Raman Research Institute (RRI) in Bangalore, where he continued his research till his death in 1970 at the age of 82. C.V. Raman death anniversary is on 21st November which is remembered for his excellence in the field of Physics. 

C.V. Raman's death on November 21, 1970, marked a significant loss for the scientific community. However, his contributions to science remain indelible, and his legacy continues to inspire and guide scientists around the globe. On this day, we commemorate his remarkable achievements and honor his unwavering dedication to the pursuit of knowledge.
