CREST
They don't. They only relate to transverse waves, not longitudinal waves.
Transverse waves have crests and troughs. Longitudinal waves have compressions and rarefactions.
Transverse wave has crests and troughs. But longitudinal has only compressions and rarefactions. Any way while drawing figures even for longitudinal as in the case of organ pipes we follow only crest and trough structures.
Condensation is the increase in density in a longitudinal wave, thus it signifies a high pressure area, which is higher energy, which is equated to the crest of a transverse wave.

The distance from crest to crest in a transverse wave is called a wavelength.

That's a description of "wavelength".
