One of the most prominent
Indian scientists in history, C.V. Raman was the first Indian person to win the
Nobel Prize in science for his illustrious 1930 discovery, now commonly known
as the “Raman Effect”. It is immensely surprising that Raman used an equipment
worth merely Rs.200 to make this discovery. The Raman Effect is now examined
with the help of equipment worth almost millions of rupees.
EARLY LIFE:
Chandrashekhara Venkata
Raman was born on November 7, 1888 in Tiruchinapalli, Tamil Nadu. He was the
second child of Chandrasekhar Iyer and Parvathi Amma. His father was a lecturer
in mathematics and physics, so he had an academic atmosphere at home. He entered
Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination,
winning the first place and the gold medal in physics. In 1907, C.V. Raman
passed his M.A. obtaining the highest distinctions.
During those times there
were not many opportunities for scientists in India. Therefore, Raman joined
the Indian Finance Department in 1907. After his office hours, he carried out
his experimental research in the laboratory of the Indian Association for the
Cultivation of Science at Calcutta. He carried out research in acoustics and
optics.
Contributions and Achievements:
In 1917, Raman
was offered the position of Sir Taraknath Palit Professorship of Physics at
Calcutta University. He stayed there for the next fifteen years. During his
tenure there, he received world wide recognition for his work in optics and
scattering of light. He was elected to the Royal Society of London in 1924 and
the British made him a knight of the British Empire in 1929. In 1930, Sir C.V.
Raman was awarded with Nobel Prize in Physics for his work on scattering of
light. The discovery was later christened as "Raman Effect".
In 1934, C.V.
Raman became the director of the newly established Indian Institute of Sciences
in Bangalore, where two years later he continued as a professor of physics.
Other investigations carried out by Raman were: his experimental and
theoretical studies on the diffraction of light by acoustic waves of ultrasonic
and hypersonic frequencies (published 1934-1942), and those on the effects
produced by X-rays on infrared vibrations in crystals exposed to ordinary
light. In 1947, he was appointed as the first National Professor by the new
government of Independent India. He retired from the Indian Institute in 1948
and a year later he established the Raman Research Institute in Bangalore
Later Life and Death:
Sir C.V. Raman became the
Fellow of the Royal Society of London in 1924. A year later, he set up Raman
Research Institute near Bangalore, where he continued the scientific research
until his death which was caused by a strong heart attack on November 21, 1970.
His sincere advice to aspiring scientists was that “scientific research needed
independent thinking and hard work, not equipment.”
