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，发射的光电数量也在增加。

When these photons strike the surface, they knock electrons off it; we call these photoelectrons.

当这些光表时，把电开；我称之为光电。

And in chemistry, in science, we can actually measure ionization energy using something called photoelectron spectroscopy.

在化学和科学领域，我实际上可以使用光电能谱来测量电离能。

And so what's cool about photoelectron spectroscopy is we can actually verify the predictions that we made with Coulomb's Law.

因此, 光电光谱的酷之处在于, 我实际上可以验证我用库仑定律做出的预测。

That technology is called photoelectron spectroscopy.

这项技术被称为光电能谱。

If we're looking at a sample of hydrogen we're going to create a spectrum or a photoelectron spectrum.

如果我正在观察氢样本，我将创建一个光谱或光电谱。

The electrons which are emitted during such a process are called photoelectrons.

在这样的过程中发射出来的电被称为光电。
