| 摘 要： | 分析了现有理论推导出的光电流与入射光频率定量关系,用普朗克常数测定仪实测了反向遏制电压为(零电场)时Ag-O-K光电管光电流在不同频率但相同光强作用下随入射光频率变化的曲线,并与理论推导的结论进行了比对和讨论分析。

| Abstract: | Theoretical research of relation between photocurrent and light power ＆ frequency is discussed in this paper. Via Plank constant measuring apparatus, adjusting the inverse repulsive voltage to zero,related experimental curves of Ag-O-K tube＇s photocurrent and incident light frequency are achieved,and comparisons between theoretical analyses and experimental data are also discussed. |
