Meanwhile, he continued to carry out different types of experiments and researches on the sun rays passing through water, transparent ice blocks, and other media. For these experiments, Raman used a mercury arc and a spectrograph. Raman obtained some new lines in the; spectrum on passing the sun rays through different substances. These lines were later called ‘Raman Lines’ and this discovery the ‘Raman Effect’. For this discovery, he was awarded the Nobel Prize in Physics in help in the industrial development of the world. The government of India the same discovery. This discovery of Raman rendered the most valuable 1930.
