所谓光电效应,就是在光的照射下,物体发射电子的现象,光电效应很好地揭示了光具有粒子性.学好这部分内容可以为学习量子论知识打下扎实的基础.光电效应中主要包含着以下三个学习要点:1.光电效应现象;2.光电效应的基本规律;3.爱因斯坦光电方程.下面结合具体实例作分类例析,以求
The so-called photoelectric effect is the phenomenon that the object emits electrons under the irradiation of light. The photoelectric effect reveals that light has a particle nature. Learning this part can lay a solid foundation for learning quantum theory. The photoelectric effect mainly contains The following three learning points: 1. Phenomenon of photoelectric effect; 2. Basic law of photoelectric effect; 3. Einstein’s photoelectric equation. The following combination of specific examples for classification analysis, in order to
