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，而对应其，新声会有一个谷。

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

之间的距离称为长。

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之间并没有太大的距离。

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

声跟一样，有和谷。

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

红的长较长，之间的距离大约是紫的两倍。

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

它头上有一个绿色的, 火花像个小明星.

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

在你上方的是，在粒子正经历着它们最大的加速度。

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

如果他的超过了39度 我们就得把他送到重症监护病房了。

Well, just back from the cusp.

只要离开就行。

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

在一些地方，积累起来变得非常大；在另一些地方，它们完全抵消了。

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

的最高点叫两之间的距离叫做长。

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，并不是流动的，而是的能量运动。

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、更接近的。

The crest is the point where the river reaches its highest point.

是河流达到最高点的地方。

When it's too dark to see, he emits an ultrasound wave with tall peaks.

当天黑得看不见时，他会发出很高的超声。

Is it arriving at a peak or a trough?

它是到达还是谷？

Sometimes the peaks line up to produce a louder sound.

有时，对齐会产生更响亮的声音。

You can still clearly see the wavelength as the distance between these crests.

你仍然可以清楚地看到长，即这些之间的距离。

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

然而，当一个的遇到另一个的谷时，的强度就会下降。

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

长。上相邻两个或谷之间的距离。
