Question

If the focal length of a spherical mirror is 15cm. Find the radius of curvature

​

Answer 1

Explanation:

radius of curvature is 30cm.

Answer 2

Given:

The focal length of the spherical mirror = 15 cm

To find:

The radius of curvature of the spherical mirror.

Solution:

We know that the radius of curvature is twice that of the focal length of a spherical mirror. Thus, we can say that,

R = 2× f

Where f is the focal length of the spherical mirror. on substituting the values in the given equation, we get:

R = 2× 15 cm

R = 30 cm

The radius of curvature of the spherical mirror is 30 cm.
