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

对波的波谷，新波会有一个波，而对其波，新波会有一个波谷。

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

波之间的距离称为波长。

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

更重要的是常波前后的波之间并没有太大的距离。

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

波跟波一样，有波和波谷。

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

红的波长较长，波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波, 火花像个小明星.

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

在你上方的是波，在那里水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.

如果他的波了39度 我们就得把他送到重症监护病房了。

Well, just back from the cusp.

只要离开波就行。

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

在一些地方，波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.

波的最高点叫波两波之间的距离叫做波长。

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

它们有波谷和波，并不是流动的水，而是水的能量运动。

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、更波接近的波。

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

波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，他会发出波很高的波。

Is it arriving at a peak or a trough?

它是到达波还是波谷？

Sometimes the peaks line up to produce a louder sound.

有时，波对齐会产生更响亮的音。

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

你仍然可以清楚地看到波长，即这些波之间的距离。

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

然而，当一个波的波遇到另一个波的波谷时，的强度就会下降。

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

波长。波上相邻两个波或波谷之间的距离。
