Introduction to Waves

Question 9 • Crowley Credit Recovery Physics B

A sound wave travels through water. What best describes the direction of the water particles?

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

Explanation

Sound in water is a longitudinal wave, so water particles vibrate back and forth parallel to the direction the wave travels. The vibrating source pushes and pulls the nearby water in that same direction. The particles oscillate rather than traveling along with the sound wave, so choice B is the best description.
