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

它不仅记录光强度，而且也记录入光的方向。

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

冰晶将太阳的入光太空，这对大气产生冷却效应。

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

光谱是当你把从一个物体的入光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.

阳光入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。

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

然而，一些入光会转化为热量。

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

入角等于角。

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

对于相机来说，它是控制入光量的光圈。

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

所以，我们会说角等于入角。

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

球器不能完美地聚焦所有入光线。

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

在任何一种情况下，这些结构都像入光子的迷宫。

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

因此，我们可以说角 等于入角。

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

它的工作原理是这样的：物镜从远处接收入光线。

The overall electric field, then, looks like the initial incoming light wave added together with the second-order wave.

那么，整体电场看起来就像初始入光波与二阶波相加。

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

一束白色入光被散至无数不同的方向，而不是一个方向，按颜色依次排列。

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光不正：眼睛聚焦入光的方式存在缺陷。

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，你可以看到，随着入光强度的增加，发的光电子数量也在增加。

Eventually, she and her colleagues worked out that the dragonfish reflects just one in every 2,000 photons incident upon it-an absorbance of 99.95%.

最终，她和她的同事发现深海龙鱼仅入到其表的1/2000的光—吸光度为99.95%。

Well, our tennis is definitely the higher the better, because the higher you are, the greater the angle of incidence.

嗯， 我们的网球绝对是越高越好，因为你越高， 入角就越大。

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

为了使这种错觉发挥作用，入角必须等于角。

When some are aimed at you, they appear black because they're absorbing most wavelengths of incoming light — but there's no actual opening.

当它们瞄准你的时候，它们看起来是黑色的，因为它们吸收了入光的大部分波长——但没有实际的开口。
