双棱镜干涉实验的深入研究

Intensive Study of Double Prism Interference Experiment

实验用双棱镜获得双光束干涉的方法测量了光波的波长,解释了用双棱镜干涉测光波波长的实验原理。实验应用了钠光、汞灯、激光等光源对双棱镜干涉测光波波长,叙述了如何快速的调节出清晰的干涉条纹以及测量两虚相干光源间的距离,总结了用透镜两次成像法测两虚光源的间距的不足,测得相关实验数据,计算出相关光波的波长,并讨论了实验的相关量对实验的影响。

This experiment, by using the method of the double prism for two-beam interference to measure the wavelength of light waves, explains the experimental principle. The experiment adopts sodium light, mercury lamp and laser light to test the experimental principle, describes how to quickly adjust the clear interference fringes and how to measure the distance between the two imaginary coherent light sources, and summarizes the deficiencies to use two lens imaging method to measure the distance between two virtual light sources. The experiment also mea-sures relevant experimental data to calculate the wavelength of light waves, and discusses the relevant amounts of experiments on the experiment.
