Question

A spherical mirror used in solar furnace focuses sunlight on its principal axis at a distance 12 cm from its pole. The radius of curvature of the mirror is

20 POINTS

Answer 1

R = 24 cm

Step-by-step explanation:

Given that,

A spherical mirror used in solar furnace focuses sunlight on its principal axis at a distance 12 cm from its pole. It means the focal length of the mirror is equal to 12 cm

We need to find the radius of curvature of the mirror. Let it is R. We know that the relation between radius of curvature and the focal length is given by :

R = 2f

So,

So, the radius of curvature of the mirror is equal to 24 cm.
