Question

write relation between focal length and radius of curvature answer​

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. ... Convex mirrors are diverging mirrors .

Answer 2

Explanation:

The radius of curvature (r) is the radius of the lens that forms a complete sphere. ... Therefore, the radius of curvature is twice the focal length.
