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，和事发现深海龙鱼仅反射入射到其表面1/2000光—吸光度为99.95%。

Offshore underwater canyons or rock formations in certain locations like Nazare, Portugal or Mavericks, California , refract the incoming wave energy into a single spot, creating massive waves sought by surfers worldwide.

近海水下峡谷或岩层在某些地方，比如葡萄牙纳扎尔或是加利福尼亚Mavericks，将入射波浪能量折射到一个地点，从而创造出全世界冲浪者所追求巨大波浪。

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

当它们瞄准你时候，它们看起来是黑色，因为它们吸收了入射光大部分波长——但没有实际开口。

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，你可看到，随着入射光强度增加，发射光数量也在增加。

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

冰晶将太阳入射光反射回太空，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入射光分成单独颜色或波长时产生结果。

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

它不仅记录光强度，而且也记录入射光方向。

If the energy of the incident photons is less than the work function, no electrons will be emitted, regardless of the intensity of the light.

如果入射光能量小于功函数，则无论光强度如何，都不会发射出。

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

阳光入射角度在真正决定了冬和夏冷热差别，而非距太阳远近。

Twinkling happens because the air over our heads is turbulent, and as it blows past, it distorts the incoming light from stars, making them appear to slightly shift position and brightness several times per second.

星星之所会闪烁，是因为我们头顶上空气是湍流，当它吹过时候，会扭曲来自恒星入射光，使它们位置和亮度每秒发生几次轻微改变。

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

对于相机来说，它是控制入射光量光圈。

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

它能吸收约99.4%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迷宫。

And then we are going to measure the amount of light that is coming.

然后我们要测量入射光量。

When an electromagnetic wave from the satellite is directed towards DISHI, the electric fields from this incoming signal will influence the electrons in the copper patch, thus generating an oscillating flow of electrons.

当来自卫星磁波朝向DISHY时，该入射信号产生场会影响铜片中，从而产生振荡流。

But once the ray reaches the interface between the glass and the air on the other side, it refracts again, and now the angle of refraction is equal to that first incident angle.

但一旦光线到达玻璃和另一侧空气界面时， 它再次发生折射，此时折射角等于最初入射角。

And to build a little intuition, take a moment to think about what would happen if the frequency of the incoming light was something very close to the resonant frequency of this oscillator.

为了建立一些直觉，花一点时间思考一下，如果入射光频率非常接近这个振共振频率，会发生什么。

But some hold most of their negatively-charged electrons closer to one side, lending them a lopsidedness that can jiggle back and forth to absorb the energy of incoming infrared rays.

但是有些人将大部分带负保持在靠近一侧位置，从而使它们不平衡， 可来回摇晃吸收入射红外线能量。

The positions of these spots seem to depend on simple numerical relations, and on the mode in which the crystal presents itself to the incident stream.

这些斑点位置似乎取决于简单数值关系，及晶体相对于入射束取向方式。

Its direction a process called refraction The angle through which it is refracted depends on its angle of incidence to the refracting surface and angle.

它方向改变被称为折射，折射角度取决于它入射到折射表面角度。
