What are the parts of a transverse wave?There are two parts to a transverse wave, the crest and the trough.

Draw and label the sketch below.

The grey line is the rest position. You can think of this as the water in a calm lake.

What are the parts of a longitudinal wave?

There are two parts to a longitudinal wave, the compression and the rarefaction.

Draw and label the sketch below.

The compression is where the slinky is squeezed together. The rarefaction is where the slinky is stretched out.

VOCABULARYTransverse wave-the medium moves at right angles to the direction of

the wave

Crest- the high part of a transverse wave.

Trough-the low part of a transverse wave.

Longitudinal wave-the medium moves in the same direction as the wave.

Compression-the part of a longitudinal wave where the medium is close together.

Rarefaction-the part of a longitudinal wave where the medium is far apart.
