Question

write a relation between focal length and centre of curvature​

Answer 1

Explanation:

The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature. It is important to note up front that this is an approximately true relationship.
