Question

a angle of reflection for a ray of
light falls normally on a plane surface​

Answer 1

Answer:

Explanation:

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.
