We regulate the wavelength of light.

我们还对光的波长进行调控。

Remember, redshift stretches the wavelength of light.

记住，红移延伸了光的波长。

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

大气中的不同气体会吸收不同波长的光。

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。

The color, the wavelength, of light emitted changes as the bar heats up.

光的颜色、波长会随着棒加热而改变。

What we see as different colours are actually different wavelengths of light.

各种不同的颜色本质上是不同波长的光。

Depending on the wavelength of light we can see different features on the sun.

取决于光的波长，我们可以在太阳上看到不同的特征。

But we're looking at wavelengths of light year to a few light years.

但我们看到的波长为 1 光年到几光年。

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。

Is green just Nature's favorite color, or is there something special about those wavelengths of light?

难道绿色是大自然最喜爱的颜色，还是这些光波有什么特别之处？

Visible wavelengths of light are just a tiny fraction of all the light in the universe.

可见光的波长在所有光波中只占了很小一部分。

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

我们之所以看到的是白色，是因为北极熊毛发中空部分对光线的折射造成的。

If an object is headed toward you, the wavelength of light from the source gets compressed, shorter.

如果一个物体靠近你，来自这个光源的光的波长就会被压缩，变短。

Using that technology, satellites can record the specific wavelengths of light reflecting off leaves thousands of miles below.

使用这项技术，卫星能记几千英里下树叶反射的特定光波波长。

Even though those particles aren't blue, they're scattering shorter blue wavelengths of light away, while redder wavelengths pass through.

即使这些粒子不是蓝色的，它们也会散射蓝色的短波，蓝色的短波被散射开来，红色的光波会直接穿过。

Infrared can pass through human tissue more easily than some other wavelengths of light, like the visible spectrum or UV.

相比其他光的长波长，红外线更加容易的穿过人体组织，比如可见光谱或UV。

Having a range of pigments that can target different wavelengths of light allows plants to harvest more energy during photosynthesis.

拥有一系列可以瞄准不同波长光线的色素可以让植物在光合作用中获取更多的能量。

And so different colours and different frequencies or different wavelengths of light, we have different responses and different reactions to them.

所以不同的颜色和频率或不同的光的波长，我们对它们会有不同的反应。

Solar panels can only interact with certain wavelengths of light, making it impossible to convert over half the sunlight they receive.

因为电板只对特定波长的光线有效，它们只能转化接受光能的一半。

Colors correspond to wavelengths of light, and the light that we call violet is different from the light we call red.

颜色对应于光的波长，我们称之为紫色的光与我们称之为红色的光不同。
