利用波动光学的牛顿环和光栅的方法、几何光学的小棱角三角杯反射法以及三棱杯最小偏向角法测量了液体的折射率,讨论实验中的一些问题并比较了各方法的优缺点和误差。最后研究了液体浓度对折射率的影响。
Measured liquid refractive index by geometrical optical methods of little angle triple-cup and minimum deviation angle method, and fluctuation methods of Newton rings and grating. The difference of these methods and something important like error was discussed. Finally refractive index influenced by concentration was also investigated.
