1波传播的距离和振动质点通过的路程的区别波在同一均匀介质中向各个方向匀速传播,波传播的距离指波在传播方向上匀速通过的距离,可用公式s=vl求出.波在一个周期内传播过的距离为一个波长.在波的传播过程中,各个质点只能在平衡位置附近振动.在一个周期内,振动质点通过的路程等于振幅的四倍(即4A). 1 wave propagation distance and vibration particles through the difference between the waves in the same uniform medium to all directions of uniform propagation, wave propagation distance refers to the wave in the direction of propagation of uniform velocity, can be obtained using the formula s = vl wave in During one cycle, the distance traveled is one wavelength. During propagation of the wave, each particle can only vibrate near the equilibrium position. In one cycle, the vibration particle travels four times the amplitude (ie, 4A).
