基于Matlab光电效应测量光速的新方法研究

摘要

Based on photoelectric effect,an experiment of measurement of light velocity in the air is designed. Light current is yielded from the surface of metal by the irradiation of different frequencies’ light,and then re-serve cut-off voltages are measured respectively,the data processing and analysis are performed via Matlab,and finally light velocity in the air is worked out.%基于光电效应，设计光在空气中传播速度测量的实验。通过不同的滤波片来实现不同的频率的光照射金属产生光电流，再测量相对应的反向截止电压，并基于Matlab进行数据处理和分析，最终计算光子在空气中的传播速度。
