Find the focal length of a convex mirror whose radius of curvature is 32 cm.

Q. Find the focal length of a convex mirror whose radius of curvature is 32 cm. 

 

Answer:-

We know,for spherical mirrors of small apertures, the radius of curvature is twice the focal length i.e. R = 2f .
Given here, radius of curvature R is 32 cm. and focal length of a convex mirror f = ?



R 32
f =
=
= 16 cm
2 2

Focal length of mirror is 16 cm
