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

对应的谷，新会有一个峰，而对应其峰，新会有一个谷。

The distance between these crests in the wave is called the wavelength.

峰之间的距离称为长。

The distance between each crest, or tip, of a wave is its wavelength.

每个峰之间的距离就是它的长。

What's more there's nevermuch distance between one ordinary wave's crest and the one following it.

更重要的是常前后的峰之间并没有太的距离。

It has a green crest on its head, which sparkles like a little star.

它头上有一个绿色的峰, 火花像个小明星.

If he spikes over 103, we need to get him up to I.C.U.

如果他的峰超过了39度 我们就得把他送到重症监护病房了。

However, you can certainly identify and measure specific characteristics of a wave pattern as a whole, most notably, its wavelength, which is the distance between two consecutive crests or troughs.

然而，你当然可以识别和测量一个型的特定特征作为一个整体，最显著的是它的长，它是两个连续峰或谷之间的距离。

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，峰对上谷，此抵消——那就是相消（破坏性）干涉。

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——尽管以光速来移动，单个引力要用十多年才能穿过我们的太阳系。

And when our eyes recognize the color blue, we're really seeing shorter, choppier light waves with peaks that are close together.

当我们的眼睛识别蓝色时，我们看到的是更短、更峰接近的光。

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

跟光一样，有峰和谷。

Red light has a longer wavelength, about twice the distance between crests as violet light.

红光的长较长，峰之间的距离约是紫光的两倍。

Well, just back from the cusp.

只要离开峰就行。

For example, when our eyes recognize the color red, what we're actually seeing is long, stretched-out light waves with peaks that are far apart.

例如，当我们的眼睛识别出红色时，我们实际上看到的是长长的、拉伸的光，峰之间的距离很远。

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，并不是流动的水，而是水的能量运动。

In some places, wave peaks add up to become very large; in other places, they completely cancel out.

在一些地方，峰积累起来变得非常；在另一些地方，它们完全抵消了。

When the additional distance it travels from one layer to the next, and back, is a multiple of the wavelength — such as 500 or 1000 extra nanometers — the crests and valleys of the waves match each other.

如果光从一层到下一层再回来所走的额外距离刚好是长的倍数——比如额外的五百或一千奈米——峰和谷就会配对上。

Above you is the wave's crest, where the water particles are undergoing their greatest acceleration.

在你上方的是峰，在那里水粒子正经历着它们最的加速度。

The top of a wave is called its crest and the distance between two crests is called the wavelength.

的最高点叫峰两峰之间的距离叫做长。

Rather  than smooth rolling waves, the surface is rough and choppy, with deep troughs and frothy crests.

表面不是平滑滚动的浪，而是粗糙且涛汹涌，有深谷和泡沫峰。
