During a voyage to Europe in 1921, Raman noticed the blue colour of glaciers and the Mediterranean sea. He was motivated to discover the reason for the blue colour. Raman carried out experiments regarding the scattering of light by water and transparent blocks of ice which explained the phenomenon.

Raman employed monochromatic light from a mercury arc lamp which penetrated transparent material and was allowed to fall on a spectrograph to record its spectrum. He detected lines in the spectrum, which were later called Raman lines. He presented his theory at a meeting of scientists in Bangalore on 16 March 1928, and won the Nobel Prize in Physics in 1930. In Munich, some physicists were initially unable to reproduce Raman's results, leading to scepticism. However, Peter Pringsheim was the first German to reproduce Raman's results successfully. He sent spectra to Arnold Sommerfeld. Pringsheim was the first to coin the term "Raman effect" and "Raman lines."
