What will be the angle of incidence when a rayof light passes through the centre of curvatureof a concave mirror?

Answer»

A ray oflight passing through the centre of curvatureof a concave mirror retraces its path (gets reflectedalongthe same path), because as the ray oflight passes through centre of curvatureof a concave mirror it strikes the mirroralongthe normal i.e. it incidences on to the mirror at 90 degree.
