A converging lens is used to form an image on a screen. When the upper half of the lens is covered by an opaque screen

A

half the image will disappear.

B

complete image will be formed.

C

intensity of the image will increase

D

intensity of the image will decrease.

Text Solution

Verified by Experts

The correct Answer is:
B, D
The image formed will be complete because light rays from all parts of the object will strike on the lower half. But since the upper half light rays are cut off, the intensity will reduce.
