In a longitudinal wave, how do particles oscillate relative to the direction of energy transfer?
Parallel to the direction of energy transfer.
How do particles move overall as a longitudinal wave passes through a medium?
They oscillate about their equilibrium positions; the medium as a whole does not need to travel with the wave.
What type of wave is sound in air?
A longitudinal wave.
In a sound wave in air, how do compressions and rarefactions differ in pressure and particle density?
Compressions have higher pressure and particle density than equilibrium; rarefactions have lower pressure and particle density.
