Question

Raman effect was discovered by which scientist?
A. Meghnad Saha
B. Birbal Sahni
C. J.C. Bose
D. C.V. Raman

Answer 1

Hint: The Raman effect is that the change within the wavelength of sunshine that happens when a beam of sunshine is deflected by molecules. When a beam of sunshine passes through a dust-free, transparent compound sample, a little a part of the sunshine is emitted during a different direction from the incident (incident) beam. Most of this scattered light incorporates a constant wavelength. However, atiny low part is different from the wavelength of the incident light; its existence is that the results of the Raman effect.

Complete answer:
This phenomenon is known as after the Indian physicist Sir Chandrasekhara Venkata Raman, who first published his observations (The Austrian physicist Adolf Smekal theoretically described this effect earlier but their work was not published). Meghnad Saha, Birbal Sahni, and J.C. Bose are the renowned scientists of India but they didn’t discover Raman effect.

Hence, the proper option is D.

Note: The pattern of the Raman line could be a characteristic of the corresponding molecular type, and its intensity is proportional to the amount of scattered molecules within the light path. Therefore, Raman spectroscopy is employed for qualitative and mensuration. Sir C.V. Raman received a Nobel prize for the discovery of Raman effect in $1930$.
