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

它们同样有很长长-一百英里或更多。

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

下哪一种电磁辐射长最短？

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

大气中不同气体会吸收不同长。

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

暗表面吸收所有长，并将其转换为热能。

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

但是LED这样智能灯会调特定长，这可能会有所帮助。

Infrared has a longer wavelength than visible light.

红外线长比可见更长。

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

所有电磁辐射都形式传播，但是不同类型辐射有不同长。

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

另一方面，亮面吸收较少，并反射其余部分。

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

人们能听到声音长 可达到50英尺。

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

然后它被一个特殊栅反射，栅将分散到不同长。

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

不同化学物质反射不同长，因此我们弄清氮、磷和碳水平。

But more wavelengths, means more energy.

但长越小，意味着能量越大。

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

我们可藉由缩小电磁长来解决问题。

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

在电磁谱中哪种具有最长长？

The image was taken in infrared wavelengths.

这张照片是用红外长拍摄。

So long wavelengths have room to resonate.

所长长有共振空间。

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

在这种能量水平下，纤激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.

实际上这是一种红外线，对于可见和红外线来说唯一区别就是长。

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

然而，还有一些长超过了红外线。

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

我们之所看到是白色，是因为北极熊毛发中空部分对线折射造成。
