Answer:
Focal length is the distance between the center of a convex lens or a concave mirror and the focal point of the lens or mirror— the point where parallel rays of light meet, or converge. The distance from the principal focus to its pole is said to be focal length of a spherical mirror. Denoted by "f". 2f=r.
