A convex lens forms a full image of the object on a screen. If half of the lens is covered with an opaque object, then :

A
the image disappears
B
half of the image is seen
C
full image is seen and of same intensity
Correct answer
D
full image is seen and of decreased intensity

Solution

If half of the lens is covered with an opaque object, then, full image is seen but intensity of image decreases.

Hence, the correct answer is option: 'D'.
