So, for every valley there is a peak, and for every peak, a valley.

对应原声波的波谷，新声波会有一个波峰，对应其波峰，新声波会有一个波谷。

See, sound waves, like light waves, have peaks and valleys.

声波跟光波一样，有波峰和波谷。

They have a trough and a crest, and consist not of moving water, but the movement of energy through water.

有波谷和波峰，并不是流动的水，是水的能量运动。

Is it arriving at a peak or a trough?

是到达波峰还是波谷？

And when a peak lines up with a trough, they cancel out.

当波峰与波谷对齐时，会相互抵消。

When one wave's peak met another's trough, though, the light's intensity would fall.

然，当一个波的波峰遇到另一个波的波谷时，光的强度就会降。

The distance between two successive peaks or troughs in a wave.

波长。波上相邻两个波峰或波谷之间的距离。

Suddenly, Lisa and her boat are falling, plummeting into the deep, dark trough of the wave.

突然间，莉萨和她的小船急，直直跌入巨浪深邃漆黑的波谷之中。

There's no more, you know, waves, like, in terms of, like, your career's going to die off.

不再有那种，你知道的，波峰波谷，就像，你的职业生涯会逐渐消退。

And there was no deliverer, because it was far from Sidon, and they had no dealings with anyone.

因地处偏远，远离西顿，与外人毫无往来，故无人施救。此地位于贝特利和赫贝龙之间的黎波谷。

That is to say, the crests of one set of waves may coincide with the troughs of the other set.

也就是说，一组波的波峰可能与另一组波的波谷重合。

So the crests of different light waves combine, and so do the troughs, forming one wave with a higher amplitude.

所以不同光波的波峰结合，波谷也结合，形成一个振幅更高的波。

Change it enough, and you'll reach a point where the crests match the valleys, making the waves cancel each other out — that's destructive interference.

改变得够多，就会达到某个点，让波峰对上波谷，让波彼此抵消——那就是相消（破坏性）干涉。

These pressure variations can be modeled by a sine wave, where the peaks represent increased pressure and the troughs represent decreased pressure.

这些压力变化可以通过正弦波建模，其中波峰代表压力增加波谷代表压力降低。

If the peak of one ripple hits the valley of a  second ripple, they will subtract each other, producing a flat surface.

如果一个波纹的波峰碰到第二个波纹的波谷，会相互抵消，产生一个平坦的表面。

But waves interfere DEstructively when one wave's crest run into the other wave's trough, and vice versa.

但是当一个波的波峰碰到另一波的波谷时，波会破坏性地干扰，反之亦然。

Waves interfere constructively when the crests of both waves end up in the same spot, and so do their troughs.

当两个波的波峰最终在同一个位置时，波会产生建设性的干扰，的波谷也是如此。

Crest to trough a single such wave could take more than a decade to pass through our solar system, despite moving at the speed of light.

从波峰到波谷——尽管以光来移动，单个引力波要用十多年才能穿过我的太阳系。

However, phase shifting would be seen as breaking up the waves' locations of the peaks and the troughs within a set of wavelengths.

然，相移会被视为打乱波峰和波谷在一组波长中的位置。

Her bow fell into the trough, and the wave stove in her bow, flooding her wheelhouse and killed a crewman and two passengers.

她的船首陷入波谷， 巨浪击碎了船首，涌入驾驶室， 导致一名船员和两名乘客遇难。
