Detailed Solution

If the focal length of a spherical mirror is

12.5 cm

, its radius of curvature will be

25 cm

.
Focal length (

f

) is the distance from the mirror at which the light rays coming parallel from infinity meet.
The Radius of Curvature

R

is defined as the radius of the sphere of which the mirror is a part.
Given,
Focal length of the spherical mirror =

12.5 cm

Focal length and the radius of curvature are related as follows:

f = \frac{R}{2}

The radius of curvature,

R = 2 \times f

= > R = 2 \times 12.5

= > R = 25 cm
