AIIMS 2019 Physics Mirrors Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Assertion: We cannot produce a real image by plane or convex mirrors under any circumstances. Reason: The focal length of a convex mirror is always taken negative.

A

If both assertion and reason are true and reason is correct explanation of assertion.

B

If both assertion and reason are true and reason is not correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Correct Answer

Option D

Detailed Explanation

Option D is correct because the assertion is false; while plane and convex mirrors do not produce real images, they can produce virtual images. The reason is also false, as the focal length of a convex mirror is indeed taken as negative, but this does not explain the assertion correctly. In contrast, concave mirrors can produce real images under certain conditions, which further invalidates the assertion. Understanding the behavior of different types of mirrors is crucial in optics, particularly in distinguishing between real and virtual images.
