摘要
利用干涉理论,研究了牛顿环装置测量平凸透镜的曲率半径问题.通过对比分析两种不同光源的实验图样,得出最佳光源是准单色钠光光源的结论.
Using interference theory, the experiment of measuring the radius of curvature of flat convex lens by Newton＇s ring is studied. It is obtained that best light source is quasi monochromatic sodium light source from comparing two experimental patterns with two different light sources.
