Question

what is the relationship between R and f in spherical mirror​

Answer 1

Answer:

where f is focal length and R is radius of curvature of the mirror. Thus the focal length of a concave mirror is one half of its radius of curvature. where f is focal and R is radius of curvature of the mirror. Thus the focal length of convex mirror is one half of its radius of curvature.
