A longitudinal wave causes the particles of a medium to move parallel to the direction of the wave.Figure 15-2b shows a longitudinal wave .Note that the motion of the spring is parallel to the direction in which the wave is moving .Thus the difference between transverse and longitudinal waves is apparent.A sound wave is an example of a longitudinal wave.

纵波能使介质中的粒子沿平行于波的方向运动.数字15-2b就表示一种纵波.注意泉水的运动方向即与这种波的方向平行.因此纵波与横波间的区别明显.声波就是一种纵波.
