1.	Read the following passage carefully. 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.’ Now answer the following questions: 1) Why was Raman equally delighted? 2) What was the ‘Excellent news’? 3) “He was lost in thoughts” – What was he thinking? 4) What was the assumption made by C.V. Raman? 5) What do you mean by ‘Compton Effect’? 6) What did A.H. Compton show? 7) Does the nature of X-rays change in the same way when pass through all kinds matter?8) “It must be true of light too” – What does ‘it’ refer to? 9) If A.H. Compton had not discovered the Compton Effect, do you think Raman would have discovered the ‘Raman Effect’? 10) What does the change of nature of X-rays depend on?
Answer» 1) “If the Compton Effect of X-rays is true. It must be true of light too.” It made C.V. Raman equally delighted. 2) The news that “Professor Compton has won the Nobel Prize” was excellent. 3) He was thinking that, if the Compton Effect of X-rays is true, it must be true of light too. 4) If Compton Effect is true of X-rays, it must be true of light too. ’ 5) The nature of X-rays changes when passed through matter. The matter was dependent on the kind of matter. The effect was known as ‘The Compton Effect”. 6) A.H. Compton showed that the nature of X- rays changes when passed through matter. 7) No. The nature of X-rays changes dependent on the kind of matter. 8) The assumption that the nature of light changes when it passes through matter. 9) From the passage we can understand that C.V. Raman had already formulated his theory and he was about to announce his ‘Raman Effect’. But the Compton Effect give him confidence. Hence I can say if Compton Effect had not been discovered C.V. Raman would have discovered his ‘Raman Effect’. 10) The nature of X-rays change when it passes through matter depending on the kind of matter.
