So, for example, we were talking about a threshold frequency as in a minimum frequency of light that you need in order to eject an electron from a metal surface.
举个例子来说,我们谈论的临界频率是,光从金属表面逐出一个电子,所需的最小频率。
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。
