Question

Perpendicular line drawn on reflecting surface at the point of incidence is called

Answer 1

Answer:

Angle of incidence

Explanation:

If we draw a line which is perpendicular to the reflecting surface at the point of incidence, this line is called the normal. As such it is an imaginary line perpendicular to the surface reflecting the light. Angle between the incident ray and the normal is called angle of incidence

Answer 2
