A ray of light passing through the centre of curvature of a concave mirror retraces its path on

Dear Student

If you draw perpendiculars to the reflecting surface at the incidence of ray of light. For all over the surface of the concave mirror thesr perpendiculars meets at focus of a concave mirror.  That means if a ray passing through focus it is like light falling on a surface perpendicularly. So it will retraces on its reflection.
