Question

the radius of curvature of a spherical mirror is equal to half its focal length. true or false​

Answer 1

Answer:

No approximation is required for this result, so it is exact. However, as discussed above, in the small-angle approximation, the focal length of a spherical mirror is one-half the radius of curvature of the mirror, or f=R/2
