- So most of you recognize, if we switch back to the notes, that they do have a negative electron affinity.

看来大部人都想到了，如果你翻翻讲义的话，它们的电子亲和能确实是负的。

I don't think they ever actually switch back.

我不认为他们能够真正地做起来。

So let's switch back to our class notes and look at what this means.

让我们转到课堂讲义上来看看这意味着什么。

So, let's -- okay, so, why don't you all think about would happen -- we'll start with the thought exercise. You can switch back to my lecture notes then if this isn't going.

好吧，那你们想想会,发生什么，我们来想想,这个问题，如果那个不行的话,你可以转到我的讲义上来了。

So let's do a sample calculation now using this Rydberg formula, and we'll switch back to emission, and the reason that we'll do that is because it would be nice to actually approve what we just saw here and calculate the frequency of one of our lines in the wavelength of one of the lines we saw.

让我们用Rydberg公式,做一个例题，我们回到发射上,这么做是因为这样,可以用我们看到的波长,来验证我们计算的频率。
