电磁波通过两种透明介质的分界面时,反射波、折射波和入射波的电矢量分量的大小和方向之间的关系可由菲涅耳公式说明,作者通过分析和推导,给出了菲涅耳公式的几何图示,这使得在分析光学问题时,变得简单和直观.
When the electromagnetic 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.The geometric illustration of Fresnel formula,and its applications are given.
