摘要
讨论了菲涅耳双棱镜实验中距离参数对两虚光源距离和干涉区域的影响,得到干涉条纹间距与距离参数的关系式,并给出实验中距离参数的推荐值.理论分析与实验数据符合较好.
The distance parameter is discussed in the Fresnel double prism experiment. The separation of the two virtual coherent sources and the spacing of the fringe on a screen are studied. The expression of the distance between two interference fringes is derived by using the distance parameter. The optimum is recommend. It is much correspondence between theoretical analyse and experimental data.
