Chapter 13 wave motion and sound 波速ν:波动过程中,某一振动状态(即振动 相位)单位时间内所传播的距离(相速) Wave velocity: is the velocity at which wave crests(or any other part of the waveform) move. Wave velocity often referred to as the phase velocity(波速v即相速), The distance of an oscillatory state propagating in a unit-time, in one t is the wave moves a distance of a wavelength. so v=A/T=nfChapter 13 Wave Motion and Sound Wave velocity often referred to as the phase velocity (波速v 即相速), The distance of an oscillatory state propagating in a unit-time, in one T, is the wave moves a distance of  —— wavelength,so v =  /T = f  波速v ：波动过程中，某一振动状态（即振动 相位）单位时间内所传播的距离（相速）.
