Question

A ray of light falls normally on a plane mirror. What is the angle of incidence?

ANSWER FAST...​

Answer 1

Answer:

0o

When a ray of light falls normally (or perpendicular) on the surface of a plane mirror, it means that angle of incidence is 0o. According to second law of reflection, angle of incidence is equal to the angle of reflection. ... Thus, the light ray will be reflected back along the same path.

Zero

Explanation:

When a ray of light falls normally (or perpendicularly) on the surface of a plane mirror, it gets reflected along the same path because the angles of incidence and reflection are both equal to zero.
