Introduction
Chandrasekhara Venkata Raman, popularly known as C.V. Raman, was a renowned Indian physicist whose groundbreaking work on light scattering earned him the Nobel Prize in Physics in 1930. His discovery, known as the Raman Effect, revolutionized the study of molecular interactions with light and paved the way for numerous scientific advancements.
Early Life and Education
C.V. Raman was born on November 7, 1888, in Tiruchirapalli, Madras Presidency (now Tamil Nadu, India). From an early age, he showed exceptional talent in academics, particularly in science and mathematics. He pursued his higher education at Presidency College, Madras, where he earned his bachelor’s and master’s degrees in physics, securing top honors.
Career and Scientific Contributions
Raman’s scientific journey began when he joined the Indian Finance Service but soon transitioned to full-time research. His major contributions include:
The Raman Effect
- In 1928, while experimenting with light scattering, Raman discovered that when light passes through a transparent material, it changes in wavelength due to interaction with molecular vibrations. This phenomenon was later named the Raman Effect.
- This discovery confirmed the quantum nature of light and provided crucial insights into molecular structures.
- The Raman Spectroscopy technique, developed from his findings, became a vital tool in chemistry, physics, and material sciences.
Other Notable Works
- Conducted extensive research on acoustics and the physics of musical instruments.
- Studied the diffraction of light and the behavior of liquids.
- Established the Indian Journal of Physics and contributed significantly to the growth of scientific research in India.
Awards and Recognition
C.V. Raman received numerous accolades for his contributions to science, including:
- Nobel Prize in Physics (1930) – First Indian and first Asian to win a Nobel Prize in science.
- Bharat Ratna (1954) – India’s highest civilian award.
- Fellow of the Royal Society (1924) – One of the highest honors in the scientific community.
