CV Raman Biography: Wiki, Contribution to Science & Inventions

CV Raman Biography is an inspiring story of a great Indian physicist who made one of the most important discoveries in science. Sir CV Raman was born in Tiruchirappalli in the Madras Presidency of British India (now Tiruchirapalli, Tamil Nadu, India) to Tamil Iyer Brahmin parents, Chandrasekhar Ramanathan Iyer and Parvathi Ammal. He was the second of eight siblings. His father was a teacher at a local high school and earned a modest income.

He recalled: “I was born with a copper spoon in my mouth. At birth, my father earned the magnificent salary of ten rupees per month!” In 1892, his family moved to Visakhapatnam (then Vizagapatam or Vizag) in Andhra Pradesh as his father was appointed to the physics faculty at Mrs A.V. Narasimha Rao College.

This CV Raman Biography offers an in-depth look at his life, career, and the remarkable impact he’s made.

CV Raman Biography

Raman was educated at the St Aloysius’ Anglo-Indian High School, Visakhapatnam. He passed matriculation at age 11 and the First Examination in Arts examination (equivalent to today’s intermediate examination, pre-university course) with a scholarship at age 13, securing first position in both under the Andhra Pradesh school board (now Andhra Pradesh Board of Secondary Education) examination.

In 1902, Raman joined Presidency College in Madras (now Chennai), where his father was transferred to teach mathematics and physics. In 1904, he obtained a B.A. from the University of Madras, where he stood first and won the gold medals in physics and English. At age 18, a graduate student, he published his first scientific paper on “Unsymmetrical diffraction bands due to a rectangular aperture” in the British journal Philosophical Magazine in 1906.

In 1907, he earned an M.A. from the same university with the highest distinction. His second paper, published in the same journal that year, was on the surface tension of liquids. Along with Lord Rayleigh’s paper on the ear’s sensitivity to sound, Lord Rayleigh started communicating with Raman, courteously addressing him as Professor.

Aware of Raman’s capacity, his physics teacher Rhishard Llewellyn Jones insisted he continue research in England. Jones arranged Raman’s physical inspection with Colonel (Sir Gerald) Giffard. Raman often had poor health and was considered a “weakling.” The inspection revealed that he would not withstand the harsh weathers of England, the incident of which he later recalled, and said, “[Giffard] examined me and certified that I was going to die of tuberculosis… if I were to go to England.”

Career and Research

After completing his education, Dr CV Raman joined the Indian Finance Department. However, his passion for scientific research led him to continue experiments in physics. While working at Calcutta University, he became deeply interested in light scattering. In 1928, he made his most significant contribution to science by discovering the Raman Effect. This discovery led him to win the Nobel Prize in Physics in 1930.

CV Raman Inventions

C V Raman’s most famous invention was the Raman Effect, which explains how light interacts with molecules and changes its wavelength. This discovery led to Raman Spectroscopy, a powerful tool in physics and chemistry. Dr Chandrasekhara Venkata Raman also conducted studies on the acoustics of musical instruments and the blue colour of seawater.

C V Raman’s Contribution to Science

Sir Chandrasekhara Venkata Raman made many contributions to scientific research. His work in optics and light scattering changed our understanding of physics. The Raman Effect is widely used in chemistry, biology, and medicine. He also established the Raman Research Institute in Bangalore to encourage young scientists to continue physics research.

Awards and Honors

Sir CV Raman received many awards for his significant contributions to science. Some of his notable awards include:

• Nobel Prize in Physics (1930)
• Bharat Ratna, India’s highest civilian award (1954)
• Franklin Medal (1941)
• Lenin Peace Prize
• Hughes Medal
• CV Raman Award for scientific excellence
