Answers
Answer:
On the busy Bowbazaar Street in Calcutta there was an
old building. It was the headquarters of the Indian Association
for Cultivation of Science. In December, on a fine evening in
1927, there was much excitement in one of its laboratories.
Chandrasekhar Venkata Raman was showing a visitor some of
his instruments when a young man, K.S.Krishnan, rushed in and
announced, “Professor Compton has won the Nobel Prize.”
Raman was equally delighted. “Excellent news,” he said,
smiling at the visitor and then he was lost in thought. “But ….
look here, Krishnan,” he said turning to the young man, “if this
Compton Effect is true of X-rays, it must be true of light too.”
A few years earlier, A.H.Compton had shown that the
nature of X-rays changes when passed through matter. The
change was dependent on the kind of matter. This effect was called the ‘Compton Effect.’
Could light also change its nature when passed through a transparent medium? That
was the question that Raman asked himself. For five years he had been doing research in
optics, the science of light. No sophisticated equipment was available in his laboratory, but
Raman was confident that he could find the answer with some modifications in his equipment.
Four months later, on March 16, 1928, Raman announced his discovery of ‘new
radiation’ (describing the behaviour of a beam of light passing through a liquid chemical) to
an assembly of scientists at Bangalore (now called Bengaluru).
The world hailed the discovery as the ‘Raman Effect’. For scientific research in this
country, it was a red-letter day. His discovery caught the attention of the world. With
equipment worth hardly Rs. 200/- and limited facilities, Raman was able to make a discovery
which won him the Nobel Prize in physics in 1930.
Raman was born on
November 7, 1888, at
Tiruchirapalli in Tamil Nadu. His
father was a physics teacher in a
college. He was a brilliant
student right from the start. When
Raman passed his matriculation,
his parents were keen to send him
abroad for higher studies. But on
medical grounds, a British
surgeon advised them against it
and Raman stayed in the country
to do the M.A. course at
Presidency College in Madras
SCERT TELANGANA
(now called Chennai).
