Question

If the incident ray is falling along the normal
on a plane mirror, what will be the path of a
reflected ray? Retrace its
path
​

Answer 1

Answer:

The angle of incidence is equal to the angle of reflection. If the incident ray falls along the normal to a surface, it will be reflected along the normal i.e., the right ray will retrace its path.

Answer 2

Answer:

The angle of incidence is equal to the angle of reflection. If the incident ray falls along the normal to a surface, it will be reflected along the normal i.e., the right ray will retrace its path.
