They also have very long wavelengths—a hundred miles or more.

它们同样有很长的波长-一百英里或更多。

Which of these types of electromagnetic radiation has the shortest wavelength?

以下哪一种电磁辐射的波长最短？

Different gases in that atmosphere would absorb different wavelengths of light.

大气中的不同气体吸收不同波长的光。

Dark surfaces absorb all wavelengths of light and converts them to heat.

暗表面吸收所有波长的光，并将其转换为热能。

But smarter lighting—like LEDs that dial down certain wavelengths—could help.

LED样的智能灯光调特定的波长，可能有所帮助。

Infrared has a longer wavelength than visible light.

红外线的波长比可见光更长。

All electromagnetic radiation travels in waves, but different types have different wavelengths.

所有的电磁辐射都以波的形式传播，不同类型的辐射有不同的波长。

Lighter surfaces, on the other hand, absorb fewer wavelengths and reflect the rest.

另一方面，亮面吸收较少光波，并反射其余部分。

Audible sound has a wavelength that can be up to 50 feet long.

人们能听到的声音的波长 可以达到50英尺。

It then bounces off a special grating that disperses light into its different wavelengths.

然后它被一个特殊的光栅反射，光栅将光分散到不同的波长。

Different chemicals reflect different wavelengths, so we can see nitrogen, phosphorus and carbon levels.

不同化学物质反射不同波长，因此我们弄清氮、磷和碳的水平。

But more wavelengths, means more energy.

波长越小，意味着能量越大。

We can try to solve this by creating electromagnetic waves with more and much smaller wavelengths.

我们可以藉由缩小电磁波波长来解决问题。

Ten-second trivia: What type of waves have the longest wavelengths in the electromagnetic spectrum?

在电磁波谱中哪种波具有最长的波长？

The image was taken in infrared wavelengths.

张照片用红外波长拍摄的。

So long wavelengths have room to resonate.

所以长波长有共振的空间。

Fiber lasers simply aren't the right wavelength to interact with organic materials at these energy levels.

在种能量水平下，光纤激光器根本不适合与有机材料相互作用。

It's actually infrared light, and the only difference between infrared and visible light is the wavelength.

实际上一种红外线，对于可见光和红外线来说唯一的区别就波长。

Infrared isn't the end of the story. There are even longer wavelengths of light.

然而，还有一些光的波长超过了红外线。

The layers only appear white because the air spaces in each hair scatter all visible wavelengths of light.

我们之所以看到的白色，因为北极熊毛发中空部分对光线的折射造成的。
