A sound wave travels past a small dust particle floating in the air. What does the dust particle do?
It is carried along steadily in the direction in which the sound is travelling.
It stays exactly where it is, because a sound wave transfers only energy.
It oscillates backwards and forwards along the direction the sound travels.
It oscillates up and down at right angles to the direction the sound travels.
