摘要
利用PASCO实验平台对传统的光电效应实验进行改进,通过计算机实时对实验数据进行测量和采集,节省了手动记录实验数据的时间,在一堂课有限的时间内可以得到1 000组以上的实验数据,从而对光电管的光频特性和光照特性进行详细地验证与分析,并准确地测出普朗克常量.
Based on PASCO platform, the traditional photoelectric effect experiment was im- proved. The experiment could measure and record the experimental data in real-time, save the time of manually recording the data. So in one class, more than one thousand sets of experimental data could be obtained, and the optical frequency characteristics and illumination characteristics were analyzed in depth. In this experiment, the Planck constant could be measured accurately.
