解析地计算了竖直悬挂弦上横波的相速度,与直接应用张力均匀弦上的波速公式计算结果一致,从而证实了张力均匀弦上的波速公式对张力不均匀弦适用.
The wave velocity of transverse wave in vertical suspended string is calculated analytically.The result can be also obtained by using the formula of wave velocity in a spring with uniform tension,which means that the formula can be applied for a spring with uneven tension.
