Question

sum of focal length and radius of curvature of convex mirror is

a. 20cm b. 40cm c. 65cm d. 60cm​

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.
