Question

The radius of curvature is 24 object is placed at twice of focal length before mirror then find magnification

Answer 1

Explanation:

R=24

so f= 12

object distance (u)=-24

by using mirror formula

1/f= 1/v + 1/u

object is placed at centre of curvature so image formed at focus

then magnification = -v/u

1/2
