Question

A sonar wave is reflected from the ocean floor. For which angles of incidence do the wave’s angle of reflection equal its angle of incidence?

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.

Answer 2

The angles of incidence at which the wave’s angle of reflection equal its angle of incidence is 45 degrees.

What is angle of reflection?

This is the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface.

Angle of incidence is determined from snell's law;

N1sin(i) = N2sin(r)

At 45 degrees, the angle of incidence will be equal to angle of reflection.

Thus, the angles of incidence at which the wave’s angle of reflection equal its angle of incidence is 45 degrees.
