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

对应原声的谷，新声会有一个峰，对应其峰，新声会有一个谷。

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

声一样，有峰和谷。

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

它们有谷和峰，并是流动的水，是水的能量运动。

Is it arriving at a peak or a trough?

它是到达峰还是谷？

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

当峰与谷对齐时，它们会相互抵消。

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

然，当一个的峰遇到另一个的谷时，的强度就会下降。

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

长。上相邻两个峰或谷之间的距离。

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

突然间，莉萨和她的小船急速下坠，直直跌入巨浪深邃漆黑的谷之中。

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

有那种，你知道的，峰谷，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，一组的峰可能与另一组的谷重合。

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

所以同的峰结合，谷也结合，形成一个振幅更高的。

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，让峰对上谷，让彼此抵消——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建模，其中峰代表压力增加谷代表压力降低。

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

如果一个纹的峰碰到第二个纹的谷，它们会相互抵消，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.

但是当一个的峰碰到另一的谷时，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.

当两个的峰最终在同一个位置时，会产生建设性的干扰，它们的谷也是如此。

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.

从峰到谷——尽管以速来移动，单个引力要用十多年才能穿过我们的太阳系。

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

然，相移会被视为打乱峰和谷在一组长中的位置。

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。
