Question

the focal length of a spherical mirror is 25cm.Find its radius of curvature​

Answer 1

Answer:

If the focal length of a convex mirror is 25 cm, what is its radius of curvature? We know that the radius of curvature of a spherical mirror is twice its focal length. Hence, the radius of curvature of the convex mirror will be 50cm.

Answer 2

Answer:

Given,

Focal length = = 25 cm

To find : = Radius of curvature

Solution

We know that the radius of curvature of a spherical mirror is twice its focal length.

Mathematically it is given as-

Now, putting the given value we get-

Hence, the radius of curvature of the convex mirror will be 50cm.
