MHT CET 2024 Physics question

The telescopes, for a given wavelength the objectives with large aperture are used for

(A)greater magnification
(B)greater resolutionCorrect
(C)reducing lens aberration
(D)ease of manufacture

Answer: (B)

Solution

The resolving power of a telescope is , where is the diameter of the objective (its aperture). For a given wavelength, a larger aperture gives greater resolving power (the ability to separate two close objects) and also
