Question

if reflected ray is reversed and becomes new incident ray,where the corresponding new reflected ray would be?

Answer 1

If it is a plane mirror  then the incident ray is perpendicular to the  surface of the  mirror
If it is a curved mirror  then it is  perpendicular to the mirror at the pole of the mirror

Answer 2

THE ANSWER IS :

Now, if reflected ray is reversed and then incident on the mirror (it also falls normally), then the reflected ray again retraces the same path. Thus, it will be along the normal on the mirror surface. If it is a plane mirror then the incident ray is perpendicular to the surface of the mirror.

Hope you got your required answer.
