C V Raman, also known as Sir Chandrasekhara Venkata Raman, was a celebrated Indian physicist who made numerous groundbreaking discoveries and contributions to the field of physics. He is best known for his discovery of the Raman Effect, which earned him the Nobel Prize in Physics in 1930. In this article, we will take a closer look at the life and achievements of this legendary scientist.
C V Raman was born on November 7, 1888, in Tiruchirapalli, India, to a Telugu-speaking family. His father was a mathematics and physics teacher, and his mother was a homemaker. From a young age, Raman showed a keen interest in science, particularly in optics and acoustics. He completed his Bachelor of Arts degree in Physics and English from Presidency College in Chennai in 1904, and later earned his Master's degree from the same institution.
After completing his education, Raman worked as an accountant in the finance department of the Indian government. However, he soon realized that his true passion lay in research and academia. In 1917, he joined the Indian Association for the Cultivation of Science (IACS) in Kolkata as its first Palit Professor of Physics.
Raman's most significant discovery came in 1928 when he observed a phenomenon that would later be called the Raman Effect. He noticed that when a beam of light passed through a transparent material, a small portion of the light changed its wavelength and scattered at right angles to the original beam. Raman realized that this change in wavelength was caused by the molecules in the material scattering the light. This groundbreaking discovery helped to confirm the quantum theory of light and earned him the Nobel Prize in Physics in 1930.
Apart from the Raman Effect, C V Raman made many other significant contributions to the field of physics. He studied the properties of crystals, and his work led to the discovery of new crystal structures. He also worked on the theory of musical instruments, and his research helped to explain the harmonics of stringed instruments such as violins and guitars. Raman was also an expert in optics and spectroscopy, and he developed several new techniques in these fields.
C V Raman continued to work at the IACS until 1933, after which he held various positions in academia and research in India and abroad. He was the founder-director of the Raman Research Institute in Bangalore, which he established in 1948. He remained active in research and academia until his death on November 21, 1970.
C V Raman's contributions to the field of physics were immense and far-reaching. His discovery of the Raman Effect revolutionized the study of molecular structure and had numerous practical applications, such as in medicine, forensics, and materials science. Raman's work in crystallography and optics also helped to lay the foundations for many other scientific breakthroughs. He was a true pioneer in the field of physics and an inspiration to many future generations of scientists.
