Question

Quizplus · Accepted Answer

Capillary waves are a type of wave that occurs when the restoring force is due to surface tension, as opposed to wind or gravity. When a capillary wave is formed, the surface tension of the water is responsible for the wave's movement and for returning the water to its undisturbed level. Therefore, the correct answer is choice D, surface tension.
