So, one thing they did, because it was so easy to measure kinetic energy of electrons, is plot the frequency of the light against the kinetic energy of the electron that's coming off here. And in your notes and on these slides here, just for your reference, I'm just pointing out what's going to be predicted from classical physics.

他们做的其中一件事,因为测量电子动能是很容易的，就是画出光的频率,和出射电子动能之间的关系,在讲义的这里，仅仅是,为了做个比较，我要指出，经典物理所给出的预测,这个不作为对你们的要求。

Some students find that they benefit from printing out the PowerPoints and they can just take their notes along with the slides as I go and that's one way to do it, but feel free to do it whatever way works for you, but those should be available.

有些学生认为,把幻灯片打印出来很有好处,这样他们在我讲课的时候,只要在讲义的空白处做笔记就可以了,这不失为一种方法,不过随你们怎么做,只要觉得有用就行,以上仅供参考罢了
