But the silicon is what converts light into electricity, so you might think using so much less silicon would reduce the electrical output, but Atwater says that's not the case.

What we had just done a clicker question on is discussing light as a particle and the photoelectric effect, so we're going to finish up with a few points about the photoelectric effect today.
我们刚才做得课堂表决器那个问题,是讨论光作为一个粒子以及光电效应，所以今天我们将以一些,关于光电效应的观点作为结束。

In the light of human mortality, the disinterest of the gods, the chanciness of life, what can man do to achieve happiness and immortality?
既然人生苦短,又没有什么神灵保佑,生死都只是随机事件,那我们怎么才能达到幸福和不朽呢
-
And then he just takes that narrow column of light and he admits it to a prism. And what the prism does is takes a tiny, tiny difference in wavelength and refracts it through a different angle.
他只取了那个窄光柱,然后把它对准一个棱镜，棱镜所做的就是,测量出波长的细微差别,然后从不同的角度测定它的折射度。
-
The philosopher seeks to judge those beliefs in the light of true standards in the light of what is always and everywhere true as a quest for knowledge.
哲学家追寻的是以真正的标准,来评判那些信念,鉴于追寻知识,无论在何时何地皆真的标准。
-
Do you think I should neck or not? I shall not enter the kingdom of heaven anyway so I don't see what difference it makes.'" And then she writes back, Mary Brittle: "Dear Sabbath: Light necking is acceptable, but I think your real problem is one of adjustment to the modern world.
你认为我是该做还是不该做，我反正都上不了天堂了,因此，我认为做不做都无所谓，之后她给她回信了，玛丽-巴瑞特，亲爱的萨巴斯，你的做法是可接受的，但我认为,你真正的问题是无法融入现代社会。
-
So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.
所以那意味着我们将需要,计算出从紫外光源发射出的,每个光子的能量。
-
It just checks and sees what kind of light frequencies are bouncing off the object.
只要能让它检验出,物体反射的光的频率
-
And sometimes it's a matter of factors that you need to figure out what it is, and maybe it's that there's extra light in the room we don't know about.
而且有时候它是,需要计算的一个因素，有时候这个房间里可能有,我们未知的额外的光。
-
So up to this point, before it was really established that yes, light is like a particle sometimes, there was this very strong distinction between what is light and what is matter.
所以关于这个观点，在它被真正确立之前，光有时候像粒子，在什么是光和什么是物质之间,有一个非常巨大的区别。
-
And when we look at this, it's actually split by what's called a nodal plane, which is pointed out in light orange here on this picture, but what we just mean is that there is this whole plane that separates the two lobes where there is absolutely no electron density.
我们来看这里，实际上它被一个节面分开，在这图里用淡黄色表示，这意味着这个分开,两个叶瓣的平面上,是完全没有电子密度的。
-
What is the E of visible light?
可见光的能量是多少？
-
And Einstein credited de Broglie, which is a fair statement of lifting a corner of the great veil, because really there was this fundamental misunderstanding about what the difference was between matter and light, and the reality is that they can both be like-particles and they can both show characteristics of waves.
并且爱因斯坦相信德布罗意，他做了一个公正的论述,揭开了一个伟大面纱的一角，因为关于物质和光,以前确实存在着,根本性的误解，真实情况是它们同时,具有粒子和波的特性。
-
So what we end up with for the number of photons in this laser beam of light is 2.1 times 10 to the 17 photons.
这个激光束的数目是,2，1乘以10的17次方。
-
The next thing that they wanted to look at was the actual intensity of the light and see what the relationship of intensity to kinetic energy is.
下一而他们要研究的是光的强度,看一下光强和能量之间的,关系是怎样的，我们预期。
-
That makes sense because we're losing energy, we're going to a level lower level, so we can give off that extra in the form of light. And we can actually write the equation for what we would expect the energy for the light to be.
这很合理，因为我们在损失能量,我们要到一个更低的能级去,我们要以光的形式给出额外的能量,我们可以写下光能量的方程。
-
If I went on and told you what the different incident light was, and what the electrons were ejected with, and then you could look up the ionization energy for the particular different elements, you should be able to actually determine exactly which element it is, but just with the information given, we can only narrow it down to these choices here.
如果我继续告诉大家入射光源是什么，出射电子的动能是多少，那么你可以去查一查,以上各个元素的电离能，这样你就应该能确定,这个元素到底是哪个，但是只凭题目中的信息，我们只能把范围缩小至以上几种元素。
-
So we talked about what we could see with visible light, we said that's actually the Balmer series.
我们已经说过可见光，它是Balmer系。
-
OK, so we've got UV light here, and let's see what we can see, and we lose electrons, if that's what's happening.
好了，我们已经有了紫外光源，让我们来看看能观察到什么，如果那些事情发生了，我们将会失去电子。
-
