Vedclass · Answer

(C) When light rays parallel to the principal axis fall on a spherical mirror,they reflect and converge at (or appear to diverge from) a specific point on the principal axis.This specific point is known as the Principal focus,denoted by the letter $F$.For a concave mirror,the rays actually meet at this point,while for a convex mirror,they appear to diverge from this point.

What is the point,where the rays parallel to the principal axis meet after reflection,called?
