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。

Already from this class if I told you that I gave you energies in some spectrum but they were off by a factor of four, what would you think? Maybe the Z is wrong.

从这节课开始,如果我告诉你我给了你,在某些光谱里的能量,但它们不属于四大元素之一，你会怎么想？也许Z是错的。
