Q960. In 1930, Sir C.V. Raman was awarded the Nobel Prize in Physics for his work on which of the following phenomena?
Explanation
Sir Chandrasekhara Venkata Raman received the Nobel Prize in Physics for his ground-breaking discovery concerning the interaction of light with matter. His research focused on how light changes wavelength when passing through transparent materials. This work successfully established that a fraction of light shifts frequency during the scattering process, which revolutionized the field of molecular spectroscopy.

Key facts from Science and Technology
The RPSC paper is General Knowledge and General Science, so science questions come with a strong dose of applied and recent topics.
Everyday science questions test the laws and terms of physics, chemistry and biology through examples.
Defence and space questions pair a missile, satellite or mission with its year and organisation.
Policy questions ask for the year, the body and the aim of schemes like STIP, the National Quantum Mission and BioE3.
Health, environment and agriculture are on a separate page, with their own chapters.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Science and Technology?
This page has 1113 practice MCQs on Science and Technology. Each has the correct answer, and most have an explanation.
Which chapters does the science and technology set cover?
Six chapters: basics of everyday science; computers, information and communication technology; defence and space technology in India; genetics, biotechnology and nanotechnology; science and technology policies and government programmes; and recent advances, Indian contributors and indigenisation.
Is science and technology part of the RAS Prelims syllabus?
Yes. The RPSC paper is called General Knowledge and General Science, and its syllabus lists science and technology topics along with environment, health, agriculture and government programmes, so questions can come from any of these areas.
