Today, you learned about traveling waves, and how their frequency, wavelength, and speed are all connected.

今，解行波，以及它们频率、波长和速度如何相互关联。

But you might say that it does have special powers, because it’ll demonstrate for us the physics of traveling waves.

但你可能会说它确实有特殊能，为它会为我们展示行波物理特性。

But you might say that it does have special powers, because it'll demonstrate for us the physics of traveling waves.

但你可以说它具有非凡， 为它将向我们解释行波物理学。

You might remember when we talked about traveling waves that a wave's speed is equal to its frequency times its wavelength.

你可能还记得当我们谈到行波时，波速度等于它频率乘以波长。

Remember how a wave traveling down a rope gets reflected differently, depending on whether the end of the rope is fixed or loose?

我记得行波是如何沿着绳索反射 不同，取决于党是否？
