摘要
讨论了掠入射法测定液体折射率实验中,由折射率确定的临界角对棱镜角选择范围的限制,以及当棱镜角取临界角时的物理意义,并得出了辅助棱镜角取值不同时视场范围的计算式.
The refraction index definitive critical angle limitations on the selective range of prism angle and physical meaning on the critical angle of prism angle is discussed in the experiment of measuring liquid refraction index. The field range formula with different auxiliary prism angle is found.
