Suppose the peaks of the incident and reflected disturbances in Figure 14-19 each travel along the wave path with a propagation speed of 12 m/s.With what speed does a peak of the resulting disturbance (the superposition of these two disturbances) travel along the wave path?

假设事件和被反射的干扰的峰顶在表沿波浪道路的每14-19旅行与12 m/s.的传播速度。什么速度发生的干扰(叠置这两个干扰)旅行的峰顶沿波浪道路的？？

如图14-19所示,假设入射波和反射波的波峰都以12 m/s的速度沿着传播路径移动,干涉波的波峰(两列波叠加的最大值)的将以什么速度移动呢?
