The wavelength of a wave is the length of one complete cycle of a wave. For a transverse wave, the wavelength is determined by measuring from crest to crest. A longitudinal wave does not have crest. In this case, the wavelength can be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from
A) peak to peak.
B) trough to trough.
C) wavelength to wavelength.
D) compression to compression.
