So you know that x-rays are higher frequency than UV light, for example, that means it's also higher energy than UV light, and if you think back to our photoelectric effect experiments, do you remember what type of light we were usually using for those? Does anyone remember?
你们知道,X,射线的频率比紫外光高,这意味着,它的能量也比紫外光要高,那么,请大家回想一下我们的光电效应实验,大家还记得当时我们用的是什么光源吗?,有人记得吗?
