现在来说说激光光谱学，这是你们作业的重点，激光光谱学可以非常精确地测量光谱的哪些部分被不同物质吸收。

Now, Laser Spectroscopy, which is the focus of your assignment, works by measuring very precisely what parts of the spectrum are absorbed by different substances.

So let's actually let you try another example of solving a problem that has to do with one of the spectrums.

下面请大家来看一下另一个例子,这次是一个需要大家解决的关于光谱的问题。

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。
