Question

what are the parts of a longitudinal wave?
drag these tiles and drop them in the correct blank above
crests and troughs compressions and rarefactions compressions and crests
rarefactions and troughs

Explanation:

In physics (a subfield of Natural Science), longitudinal waves are characterized by regions of compression (where particles are close together) and rarefaction (where particles are spread apart). Crests and troughs are parts of transverse waves, so the correct parts of a longitudinal wave are compressions and rarefactions.

Answer:

Compressions and rarefactions
