A diminished image of an object is to be obtained on a screen 1.0 m from it. This can be achieved by appropriately placing

A

A convex mirrorr of suitable focal length

B

A concave mirrorr of suitable focal length

C

A concave lens of suitable focal length

D

A convex lens of suitable focal length less than `0.25 m`

Text Solution

Verified by Experts

The correct Answer is:
D
Convex mirrorr and concave lens do not form real image. For concave mirrorr , `vgtu`, so image will be enlarged, hence only convex lens can be used for the purpose.
