A ray incident along normal to the mirror retraces its path. Why ?

Statement-1 : A ray incident along normal to the mirror retraces its path. Statement-2 : In reflection, angle of incidence is always equal to angle of reflection

Assertion and Reason. Mark the correct choice as:Assertion:A ray incident along normal to the mirror retraces its path Reason: In reflection, angle of incidence is always equal to angle of reflection.

A ray of light falling normally on a plane mirror retraces its path on reflection.

A ray of light incident along nirmole to the mirror to the mirror ____ its path.

A ray of light falling normal to the mirror returns along the same path.Why?

Two plane mirrors are inclined to each other at a certain angle.A ray of light first incident on one of them at an inclination of 10^(@) with the mirror retraces its path after five reflections.The angle between the mirrors is

When two plane mirrors subtend an angle theta between them, then a ray of light incident parallel to one of them retraces its path afer n reflections such that ntheta=c (where c is constant) If the angle between mirrors is 60^(@) . Then light ray retraces its path after n reflections where n is
