It is in a standing wave configuration.
是个驻波结构。
And a standing wave means there is a geometric constraint which is what?
驻波意味着有几何限制,几何限制又是什么?
A scalar wave tends to propagate as a transverse wave or a standing wave.
分级梯状波往往是以横波或驻波传播。
Well, if this thing is going to vibrate for any length of time it better be a standing wave.
好的,如果它在任意时间振动,那它就是驻波。
And if it is going to be a standing wave then this must be an integral number of wavelengths.
如果这有个驻波的话,那么周长就是个整数。
And you can think about that if you think about a standing wave, for example, where you can have amplitude at many different values of x, so an amplitude at many different distances, but you also have areas where there is a amplitude.
你们可以想象一下驻波,在不同x处,可以有不同的振幅,在不同的距离有不同的振幅,但在某些地方振幅等于0.
