Theoretical research of relation between photocurrent and light power & frequency is dis-cussed in this paper.Via Plank constant measuring apparatus,adj usting the inverse repulsive voltage to zero,related experimental curves of Ag-O-K tube’s photocurrent and incident light frequency are a-chieved,and comparisons between theoretical analyses and experimental data are also discussed.
