Question

In a mirror if the reflected ray is reversed and becomes the new incident ray , where do you think the corresponding new ray would be

Answer 1

☆heya your answer is here☆

According to you the ray is incident perpendicularly on the mirror. Now, the laws of Reflection state that the angle of incidence (i) should be equal to angle of reflection (r). These angles are always measured with respect to the normal.
So, if the ray falls through the normal, then angle of incidence is zero and thus by the above statement, angle of reflection will also be zero. Here, the ray will retraces its path and reflects back.
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.

Answer 2

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.
