Question

a ray of light falls perpendicular to the reflecting surface of plane mirror. the angle of reflection is_______​

Answer 1

Answer:

The angle incidence is the angle between the incident ray and the normal. A normal is a perpendicular line to the reflecting surface at the point of incidence.

Now in this case the angle of incidence is zero. As per the law of reflection, the angle of reflection is equal to the angle of incidence. So angle of reflection is zero.
