So, for example, in the second case, we say that we see 12 06 in terms of the kinetic energy.
比如,在第二种情况下,我们观测到,1206大小的动能。
So that would probably be de Broglie's answer for why, in fact, we're not observing the wavelength behavior of material on a day-to-day life.
所以那就可能是德布罗意关于,为什么我们无法再日常生活中,观测到物质的波动行为的答案。
It was Galileo's job, you'll remember, with his telescope to detect the otherwise undetectable spots and imperfections in this seemingly, but only seemingly, perfect moon.
你们还记得,通过望远镜,观测到这个看起来,却只是看起来完美无缺的,月亮上的黑点和缺陷,是伽利略要做的。
So that you do the experiment, you see the phenomenon, and then you see the visualization that adds things to the phenomenon that you normally can't see that are there whether or not sealed.
因此我们通过做实验,观测到现象,然后看到直观化的过程,它会将你平时看不见的物质,添加到这个现象中,让你感觉它本来就在那儿。
When we do relativity, we'll be dealing with vectors in space-time and we'll find that different observers disagree on what is this and what is that.
我们学习相对论的时侯,会涉及到时空矢量的问题,我们会发现观测者们对于观测的结果,有着不同的看法
If you have a sample with n observations, it's the summation I = 1 to n of xi/n--that's the average.
如果你有n个观测值,对Xi从i=1到n求和再除以n
So, let's take a look at the different kinetic energies that would be observed in a spectrum for neon where we had this incident energy here.
那么,让我们来看一下,在已知入射能量的情况下,可以在氖光谱中观测到哪些不同的动能。
And let's look at the final kinetic energy that we'd observe in this spectrum, which is 384 electron volts, so what is that third corresponding ionization energy?
然后让我们来看一下,在光谱中观测到的,最后一种动能,它大小是,384,电子伏,那么这相应的第三种电离能是多大?
And an electron is something where, i n fact, we might be able to, if we calculate it and see how that works out, actually observe some of its wave-like properties.
如果我们对电子做计算,并且知道如何算出来的,那么我们是可以观测到,电子的一些波动性质的。
We can do the same thing for the other observed kinetic energy.
我们还可以对观测到的,其它动能进行同样的操作。
And they didn't put their explanation of what they thought was going on, it just sort of was observing what they saw.
而且他们并没有给出解释,而是仅仅介绍了他们所观测到的内容。
And it turns out that the first kinetic energy that we would see or the highest kinetic energy, would be 12 32 electron volts.
结果是我们最先观测到的动能,也就是最大的动能,将是,1232,电子伏,那。
So let's charge it up again and see if we can check again.
让我们再次给它充电看看,是否能再次观测到。
So it turns out that we can, in fact, use the energy levels to predict, and we could if we wanted to do them for all of the different wavelengths of light that we observed, and also all the different wavelengths of light that can be detected, even if we can't observe them.
事实上我们可以用能级预测,而且如果我们想的话,我们可以,对所有观测到的光的波长预测,也可以对所有探测到的光预测,即使我们看不到它们。
And, of course, all that's left is this positive pudding. So that's not going to do anything either. And what he found when he did this experiment, was that the count rate with still 132 000 counts per minute.
剩下的是带正电的布丁,也不会产生什么影响,结果他实验上观测到,计数器测得每分钟132000下,所以到目前为止,他可以说实验。
So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.
所以这意味着转移到电子,上的能量也越大,但这并不是,我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。
