氢原子光谱在三种环境下测定里德伯常数实验结果探讨

Discussion of Rydberg constant by the hydrogen spectrum in three kinds of environment

通过比较正常实验环境下(弱光)、白炽灯和阳光光照的实验结果,分别测得的里德伯常数为10973935.6507 m^(-1)、10971967.5494 m^(-1)和10971924.9037 m^(-1),与理论给出的里德伯常数均较为吻合。三种环境下计算出的相对误差分别为0.00186%、0.0161%和0.0165%。可以看出,环境因素对氢灯光源产生了细微的影响,在弱光的情况下进行实验观测,有利于消除谱线的压力展宽,从而获得更加准确的里德伯常数测量值。

By comparing three conditions, namely, normal experiment environment （weak light）, incandescent lamp and the experimental results of ordinary light, Rydberg constant is measured as 10973935. 6507 m^-1, 10971967. 5494 m^-1 and 10971924. 9037 m^-1, respectively, which is consistent with the theory of Rydberg constant given. The Relative error of three conditions is 0. 00186%, 0. 0161% and O. 0165% respectively. Environmental factors has a subtle influence on Hydrogen spectrum experiment. In the case of weak light, more accurate Rydberg constant well be measured by eliminate Pressure Broadening of the spectral lines.
