Question

The focal length of a convex mirror used as rear view mirror in a bus is 0.6m. Find its radius of curvature

Answer 1

We know the relation between focal length (f) and radius of curvature (r) of spherical mirrors.That is -

f = r/2

or, r = 2f

Putting the values we get :

r = (2×0.6)m = 1.2 m
