NEET Physics Question - Wave Optics

Assertion (A): The stars which are not resolved in the image produced by the objective of a telescope can't be further resolved by its eye piece.

Reason (R): The primary purpose of eyepiece of telescope is to provide the magnification of image produced by the objective.

(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)

(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(3) (A) is true but (R) is false

(4) Both (A) and (R) are false

Solution:

Assertion (A) is true. The resolving power is determined by the objective; the eyepiece only magnifies the existing image, it cannot resolve features not already resolved by the objective. Reason (R) is true; the eyepiece's primary role is magnification. Reason (R) correctly explains Assertion (A).
