the distance between crests on a wave is the
Although they are not true examples of this type of wave, the waves on the surface of water approximate _ transverse _ waves. 7. The distance between two successive wave crests (or troughs) is called the. _ wavelength _ of the wave. 8. The height of a wave crest (or depth of trough) above the original undisturbed surface is called the _ amplitude _ of the wave. 9.
