This tries to record not only light intensities, but the direction of incoming light as well.

它不仅记录强度，而且也记录的方向。

A spectrum is the result when you divide the incoming light from an object into individual colors, or wavelengths.

谱是当一个物体的分成单独的颜色或波长时产生的结果。

It's the angle of the sun's rays that makes winter cold and summer hot, not our distance from the sun.

阳的角度在真正决定了冬天和夏天的冷热差别，而非距太阳的远近。

The ice crystals reflect incoming light from the sun back into space, which has a cooling effect on the atmosphere.

冰晶将太阳的反回太空，这对气产生冷却效应。

For a camera it's a diaphragm that governs the amount of incoming light.

对于相机来说，它是控制量的圈。

So, we’d say that the angle of reflection is equal to the angle of incidence.

所以我们说反角等于角。

Spherical reflectors don't perfectly focus all the incoming rays.

球面反器不能完美地聚焦所有线。

It absorbs about 99.4% of  all the light that hits it.

它能吸收约99.4%的。

In either case, the structures act like a maze for incoming photons.

在任何一种情况下，这些结构都像子的迷宫。

Some of the incoming light, however, will turn into heat.

然而，部分会转化为热量。

Yeah, the angle of incidence is equal to the angle of reflection.

角等于反角。

Unpolarized glasses only use darkened glass to absorb some of the incoming light.

非偏眼镜只使用深色玻璃 来吸收部分。

For this illusion to work the angle of incidence has to equal the angle of reflection.

为了让这个错觉生效，角必须等于反角。

In the lingo of optics, the angle of incidence doesn't equal the angle of reflection.

在学术语中，角不等于反角。

Remember the angle of incidence always equals the angle of reflection.

记住角总是等于反角。

Snell's Law also holds for the next layer, and there the ingoing angle is simply theta 2.

斯涅尔定律也适用于下一层，那里的角只是 theta 2。

Here’s how it works: The objective lens takes incoming light rays from a distant source.

工作原理如下：物镜摄取来自远处源的线。

A white incoming light is therefore scattered not in one direction, but in a number of different directions, sorted by their colors.

一束白色被散至无数不同的方向，而不是一个方向，按颜色依次排列。

Look at this graph, you can see that the number of photoelectrons emitted increases as the intensity of the incident light increases.

看这张图，可以看到，随着强度的增加，发的电子数量也在增加。

Keratomileusis corrects what are called refractive errors: imperfections in the way the eye focuses incoming light.

角膜磨镶术可以纠正所谓的屈不正：眼睛聚焦的方式存在缺陷。
