A light ray reflects from a surface. If the angle of incidence is 24°, what is the angle between the reflected ray and the incident ray at the surface?
A) 24°
B) 12°
C) 66°
D) 48°
E) 102°

Quizplus · Accepted Answer

According to the law of reflection, the angle of incidence and the angle of reflection are equal. Therefore, the angle between the reflected ray and the incident ray at the surface is 2 x 24° = 48° (as the reflected ray makes an equal angle with the normal as the incident ray does). Hence, the correct option is D.
