Leo · Answer 1

After a thorough research, there exists the same question that has the following choices.

(1) angles less than 45°, only

(2) an angle of 45°, only

(3) angles greater than 45°, only

(4) all angles of incidence

The correct answer (4) all angles of incidence.

Rodrigo Brock · Answer 2

As a general rule of wave motion and the laws of reflection for any incoming wave the angle of incidence and the angle of reflection will always be the same if the medium is constant and no refraction is taking place. This is a general rule which can be used to answer any such question.
