If lower half of a concave mirror is blackned then

A

image distance increases

B

image distance decreases

C

image intensity increases

D

image intensity decreases

Text Solution

Verified by Experts

The correct Answer is:
D
Because of doing so, aperture decreases and so, less no. of light rays produce the image and so intensity of image decreases.
