Expert Answer:

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.
