An Indian scientist won the Nobel Prize in Physics in 1930 for his studies of light scattering and the discovery of a new kind of scattering, which he named Raman scattering or the Raman effect. This effect is helpful for the compositions of solids, liquids, and gases. Furthermore, you may use it in illness diagnosis and production tracking. We know him as our Sir Chandrasekhara Venkata Raman.
C V Raman Biography:
On November 7, 1888, Tamil Brahmin parents gave birth to Sir CV Raman in Tiruchirappalli, Tamil Nadu, famous as the “C V Raman Birth Anniversary.” Sir CV Raman won the Physics departmental honors award at the University of Madras when he was just 16 years old. Sir Raman graduated from the University of Madras with a Master of Science in 1907, five years later. In 1930, Sir CV Raman won the Nobel Prize for his research on light scattering and discovering the phenomena that bear his name: the Raman Effect.
Sir CV Raman joined the Indian Finance Service as an Assistant Accountant General at 19 and worked out of Kolkata. At the Indian Association for the Cultivation of Science, the country’s first research institution, Sir Venkata Raman undertook autonomous research in his exciting study area. It made his most important contributions to the sciences of acoustics and optics. The topic of his first scientific paper, published in 1906 when he was still a graduate student, was light diffraction.
Sir CV Raman initiated studies to investigate light scattering, leading to the development of Raman Spectroscopy, which may be used to see vibrational, rotational, and other low-frequency modes in a system. The acoustics of musical instruments was another area of study for him. He and one of his students discovered that light particles had rotational momentum in 1932. Sir CV Raman was honored with India’s highest civilian honor, the Bharat Ratna, in 1954 for his groundbreaking research and scientific contributions.
Sir CV Raman was tasked with advising doctoral candidates at the University of Calcutta. The University of Allahabad, the University of Madras, the Rangoon University, the Queen’s College in Indore, the Institute of Science in Nagpur, Krisnath College, and the University of Allahabad all provided financial support for Sir Raman’s Ph.D. students. By the end of 1919, Raman had trained more than a dozen apprentices. In 1919, Sir Raman was awarded the titles of Honorary Professor and Honorary Secretary by the IACS. He described this time in his life as a “golden age.”
How did C V Raman Come up with the idea for the Raman Effect?
C V Raman’s Achievements:
Dr. C. V. Raman, The Scientific Exploration of Music One of Raman’s interests, was delving into the physics of musical sound. He was moved by Hermann von Helmholtz’s The Sensations of Tone, which he read as an undergraduate at IACS. Many of his findings and studies were published between 1916 and 1921. Transverse vibration of bowed string instruments is a concept he devised based on the superposition of velocities. One of his earlier attempts was the wolf tone on violins and cellos. He studied the effects of water drops and Indian stringed instruments on the acoustics of violins and other stringed instruments.
A piece of his titled “Experiments with mechanically-played violins” demonstrated his interest in the intersection of music and technology. C. V. Raman’s Blue-Sea Color Discovery Raman expanded his study of optics to include the analysis of light scattering in 1919. His first remarkable finding was the mechanisms by which salt water takes on its characteristic blue color. He used a Nicol prism and a pocket spectroscope to analyze the seawater.

The Raman Research Institute was founded in 1949 after Sir CV Raman departed from the Indian Institute of Science in 1948. Until his death on November 21, 1970, he led the organization as its director.
