Explanation:
A ray incident normally on a plane mirror retraces its path on reflection. ... This means that the incident Ray and the normal are coincident I.e.,the angle of incidence is equal to zero, thus the angle of reflection also will be zero. So the Ray will be reflected back in the same path

Heya!!!!
A incident ray normally on a plane mirror retraces its path on reflection because angle of incidence is equal to angle of reflection. since,
angle of incidence =90 degree
so,
angle of reflection will also be 90 degree and hence it retraces its path on reflection.
