摘要
通过对光传播过程中路径的分析,基于极值的观点分别证明了光的反射定律与光的折射定律,并在证明中阐释了从最短路程原理过渡到最短时间原理的重大意义.
Based on the view of extreme value, the reflection law and refraction law of the light are proved by analyzing the paths of light propagation. The significance of the transition from shortest path principle to the Fermat＇s principle is expounded.
