摘要
用分光计测量三棱镜折射率是一个间接测量实验,通过测量三棱镜的顶角和最小偏向角来计算获得折射率.本文通过编译程序模拟实验,描绘出偏向角随入射角、折射率变化的规律,进一步研究了最小偏向角与折射率间的对应关系.
The measurement of the refractive index of prism by spectrometer is an indirect measurement experiment, which needs the acquirement of the vertical angle and the minimum deviation angle of the prism. In this paper, we have simulated the experiment by compiler, and delineated how the deviation angle changes along with the incident angle and the refractive index. Furthermore, the corresponding relation between the minimum deviation angle and the refractive index has been researched.
