Question

19)When a ray of light falls perpendicularly on a plane mirror it is reflected at an angle
of
a)0 b)90 c)180
d)360​

Answer 1

Answer:

A. Zero is the answer

Explanation:

If light falls perpendicular to the surface of mirror, that is the angle of incidence is zero degrees then the angle of reflection is also zero. Hence the light ray will retrace its path.
