摘要
探究了弗兰克-赫兹实验的最佳实验条件及第一激发电位,通过分析实验数据得出最佳实验条件为灯丝电压3.3V,第一栅极电压1.7V,拒斥电压5.0V,得到氩原子的第一激发电位为11.543eV,并分析原因.
The first excitation voltage was studied in the Frank-Hertz experiment with different parameters,the optimum parameters were obtained.By analyzing the experimental data,the optimum parameters were as follows： filament voltage 3.3 V,the first grid voltage 1.7 V and the spurn voltage 5.0 V.The first excitation voltage for Ar atom was 11.543 eV.
