What are molecules in the compression part of a sound wave?

In: Science, Physics [Edit categories]

Answer:

Sound waves that are compressed are made of (air) molecules that are more densely concentrated - that is (ie) more molecules are packed into the space of the compressed wave than there are in the (same) space of the surrounding expanded waves.

How is a sound wave a compression wave?
As a sound wave travels it compresses the air particles around it together in order for it to travel because a wave cannot travel if the matter it uses isn't connected.
Compression happens during which part of the sound wave?
it happens during the trough
Two parts of a sound wave?
Frequency (or equivalently, wavelength) and amplitude. Frequency determines the sound's pitch (high or low). Amplitude is the volume (loud or quiet).

We can't think of a single way in which electromagnetic waves are at all connected with sound or related to it.
