An object is placed at a distance of 30 cm from the pole of a curved (convex or concave) mirror of focal length 15 cm. Then the linear magnification is

A

one for both types of mirrors

B

one only for a convex mirror

C

one only for a concave mirror

D

`(1)/(3)` for a concave mirror

Text Solution

Verified by Experts

The correct Answer is:
C
For the convex mirror linear magnification is always less than one. For a concave mirror, when u=2f, v=2f and `m=(v)/(u)=(2f)/(2f)=1`.
