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

它不仅记录光强度，而且也记录入射光的方向。

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射光分成单独的波长时产生的结果。

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

冰晶将太阳的入射光反射回太空，这对大气产生冷却效应。

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

对于相机来说，它是控制入射光量的光圈。

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

面反射器不能完美地聚焦所有入射光线。

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

它能吸收约99.4%的入射光。

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

在任何一种情况下，这些结构都像入射光子的迷宫。

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

然而，部分入射光会转化为热量。

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

非偏光眼镜深玻璃 来吸收部分入射光。

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

一束白入射光被散射至无数不同的方向，而不是一个方向，按依次排列。

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，你可以看到，随着入射光强度的增加，发射的光电子数量也在增加。

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

工作原理如下：物镜摄取来自远处光源的入射光线。

This term accounts for the fact that energy from the incoming light wave is absorbed by the material.

这一项解释了入射光波的能量被材料吸收的事实。

The incoming rays then enter through the cornea and strike the retina at the back of the eye.

然后，入射光线通过角膜进入 眼睛后部的视网膜。

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：眼睛聚焦入射光的方式存在缺陷。

The objective lens takes incoming light rays from a distant source. .

物镜从远处接收入射光线。

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，它们看起来是黑的，因为它们吸收了入射光的大部分波长——但没有实际的开口。

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

总的电场，因此，看起来像是初始入射光波与二级波叠加在一起。

Since the source is so far away, the incoming rays are considered parallel.

由于光源距离很远，入射光 线被认为是平行的。

So you need to drill in and understand exactly how much those charges wiggle in response to an incoming light wave.

所以你需要深入了解这些电荷在响应入射光波时究竟会摇摆多少。
