Question

where will be a Ray of an incident on plane mirror at right angle Thrown after reflection? ​

Answer 1

Answer:

The reflected ray will retrace its path at 90 degree

Explanation:

The angle of incidence is equal to the angle of reflection

The angle of incidence is 0 when the ray hits the plane mirror at right angle

So the reflected angle becomes 0 and the ray retraces its path through normal.
