A loudspeaker produces a sound that travels through the air to a student standing on the other side of a room.
Sound waves travelling through air are longitudinal waves. Describe how the air particles move as the sound wave passes.
Name the regions of a sound wave in which the air particles are closest together.
Name the regions of a sound wave in which the air particles are furthest apart.
The student says that the air itself travels from the loudspeaker to their ear. Explain why the student is wrong.
