How does rarefraction affects the frequency of waves ?
Answered by bobpursley
Rarefraction affecting frequency? It does not affect frequency, it affects very temporarily the density of air as air particles move apart, but immediately compress.

Rarefactions occur at intervals of one wavelength, in the case of sound waves. They are part of the wave phenomenon itself and do not affect the frequency.
