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

Half the image will disappear

Complete image will be formed of same intensity

Half image will be formed of same intensity

Complete image will be formed of decreased intensity.

Text Solution

Verified by Experts

The correct Answer is:

Because to form image only two rays are to be passed through the lens and moreover, since the total amount of light released by the object is not passing through the lens, therefore image is faint ( intensity is decreased).
