摘要
从实验的角度出发,对菲涅耳双棱镜棱脊面向单缝和背向单缝两种置放方式进行实验探究,通过对多次实验数据的分析、对比,得出只有当两次实验中的狭缝到菲涅耳双棱镜的距离L相同时实验结果在误差允许的范围内是相同的。
This article investigates the mounting ways of the edge ridges of the Fresnel double prism for the single slit and back single slit. By analyzing and comparing the experiment data, one found that when in two experimentas slits to Fresnel double prism distance L are the same tests the result in the scope which the error permits is same.
