Question

What is the relation between focal length (f) and radius of curvature (R) of a spherical mirror.​

Answer 1

Answer:

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 and  the focal length f and radius of curvature r is r = 2f.
