摘要
利用劈尖的等厚干涉测量了不同液体的折射率。在不改变劈尖夹角前提下,通过读数显微镜,分别得到劈尖在空气和液体中的干涉条纹间距ΔX_空、ΔX_液,从而运用n=ΔX_空/ΔX_液得到各液体的折射率。通过本实验,丰富了折射率测量的方式。
We use a wedge of equal thickness interference measuring the refractive indices of different liquids. Wedge angle does not change the premise,by reading microscope,they are measured in air and liquid wedge of interference fringe spacing.Apply the formula n = ΔXair/ΔXliquid to obtain refractive index of the liquid.Through this experiment,it adds a good method for measuring the refractive index.
