摘要
光波通过两种透明介质的分界面时,反射光、折射光和入射光的电矢量分量的大小和方向之间的关系可由菲涅耳公式得出。本文通过理论分析和数值计算,给出了菲涅耳公式的振幅比随入射角的变化关系直观图以及光能的守恒关系。
When the light wave goes through the boundary of two different transparent medium, the relation between the amplitude of electricity vector of reflected light, refracted light and incident light and its direction can be illustrated by Fresnel formula. It showed graphs of the distribution of light power with incident angle by numerical calculation, and validated the conservation of light energy by theoretical analysis and numerical calculation.
