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). Now answer the following questions : 1) What was the question Raman asked himself?2) How long had he been doing research on light? 3) What do you mean by optics? 4) What was the setback faced by C.V. Raman in his research? 5) How was C.V. Raman able to find solution to his problem? 6) When did Raman announce his discovery? 7) What was the discovery made by C.V.
