本文利用菲涅耳公式讨论了光在两种透明介质界面上反射和折射时,反射光和折射光与入射光振幅及强度的关系,纠正了一些教科书中对“分振幅”概念的错误理解.
This paper discusses the relationship between the reflected light and the refracted light and the amplitude and intensity of incident light when the light is reflected and refracted at two kinds of transparent media interfaces by using the Fresnel formula and corrects the misunderstanding of the concept of “sub-amplitude” in some textbooks.
