摘要
以光电效应有关理论为基础,通过对光电效应基本实验事实的实验操作与探究,来验证爱因斯坦的光电效应方程,进而利用已得实验结论对普朗克常量以及截止频率进行较为精准测量;分析实验过程中的影响因素,对实验进行相关优化。
Based on the theory of photoelectric effect, we validate Einstein＇s photoelectric effect equation by experimenting and investigating the basic facts of photoelectric effect, and then uses the conclusion to accurately measure Planck constant and cut - off frequency .After analyzing the influence factors and comparing different data processing methods,then give some improvements to this experiment.
