摘　　要：用菲涅耳双棱镜测光波波长实验是大学物理实验中的基础实验,它是用分波面法获得相干光的典型实验.在实验装置中,双棱镜的放置方式有2种,即棱镜棱脊面向单缝还是背向单缝.本文通过详细的理论推导,得出双棱镜的放置方式对实验结果没有影响的结论,而且这个结论已得到了实验的证实.The light wavelengths experiment using the Fresnel double prism is basic in university physics experiment. It is a sub-wave-front method to obtain coherent light. In the experiment, the double prism is placed in two different ways, depending on whether the prism ridge faces the single- slit or not. In this paper, a detailed theoretical analysis shows that the placement method of the double-prism has no significant effect on the experiment results, and this conclusion has been confirmed by experiments.
