Question

If the radius of curvature of a mirror increases then does its focal length also increase?​

Answer 1

ANSWER-

how focal length decreases if curvature increases? ... If the spherical mirror starts curving in then the radius of the sphere decreases which then affects the focal length too.

Answer 2

Answer:

Here's Your Answer

Explanation:

Higher angles of curvature lead to shorter focal lengths due to the fact that light waves are refracted at a greater angle with respect to the optical axis of the lens.
