I.
Read the following paragraph and answer
the questions.
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 behavior 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 the 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 Tiruchurapalli in Tamil Nadu. His
father was a college physics teacher. 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.
