Question

010. a. What will be the angle of incidence when an incident ray falls on a plane mirror along
the normal?​

Answer 1

Explanation:

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:

Zero

Explanation:

Angle of incidence is angle made by incident ray with normal. Normal is perpendicular drawn to surface of mirror or lens. If light fall perpendicular on plane mirror, angle made by light with normal is zero i.e. angle of incidence is zero.
