Question

A longitudinal wave passing through a medium causes areas of:

A.
disturbance and energy.

B.
compressions and rarefactions.

C.
wavelengths and amplitudes.

D.
crests and troughs.

The answer is B. Compressions and rarefactions.

Step-by-step explanation:

• Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction.
