Question

What is true about surface waves?

A. The disturbance does not have a specific motion.
B. The disturbance is in a circular motion.
C. The disturbance is only perpendicular to the motion of the wave.
D. The disturbance is only parallel to the motion of the wave.

Answer 1

B. is the correct answer

Answer 2

Answer: The correct answer is B.

Explanation:

In longitudinal wave, the vibrations of the particle of the medium is parallel to the direction of the motion of the wave.

In transverse wave, the vibrations of the particle of the medium is perpendicular to the direction of the motion of the wave.

In surface wave, the particles of the medium undergo circular motion. The surface wave is neither longitudinal nor transverse.

Therefore, surface waves are the disturbances which travel in the circular motion.
