Asound wave travels through water. what best describes the direction of the water particles?

the water particles move perpendicular to the source of the sound wave.
the water particles move in the same direction as the vibrating source of the sound wave.
the water particles move in random patterns because the sound is diffracted in many directions.
the water particles do not move because the sound wave does not have enough energy.

The water particles move in the same direction as the vibrating source of the sound wave.

Explanation:

In transverse wave, the particles move up and down perpendicular to the direction of the motion of the wave. Light is a transverse wave.

Sound is a longitudinal wave for which the medium particles vibrate along the direction of the motion of the wave. Thus, when the sound wave travels through water, the water particles would  vibrate to and fro in the same direction as the vibrating source of sound wave.

explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
