You'll see light coming out, but it's, of course, going to be bulk light -- you're not going to be able to tell the individual wavelengths.

你会看到有光出来，但当然这些光是混在一起的,你不能看到每个单色光。

So, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.

让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。
