MHT CET 2024 Physics question

A person is observing a bacteria through a compound microscope. For better analysis and to improve the resolving power he should

(A)increase the wavelength of light
(B)increase the refractive index of the medium between the object and objective lensCorrect
(C)decrease the focal length of the eye-piece
(D)decreases the diameter of the objective lens.

Answer: (B)

Solution

The resolving power of a microscope is (inverse of the minimum resolvable separation ). It increases when the wavelength is decreased or when the refractive index of the medium between
