对光的干涉的理解不少同学总感觉很模糊,下面笔者就对这一问题从几个方面进行简单分析,以供参考.一、对光的干涉的几点理解1.现象:两列相干光波在相遇的区域内叠加,形成“有明有暗,明暗相间”的干涉条纹.2.产生光的干涉条件为:两个振动情况总是相同的光源叫相干光源,只有相干光源发出的光互相叠加,才能产生干涉现象,在屏上出现稳定的亮暗相
The understanding of light interference Many students always feel very vague. The following author briefly analyzes this issue from several aspects for reference. First, some understanding of light interference 1. Phenomenon: two columns of coherence The light waves are superimposed in the area where they meet, forming “intersecting and dark, bright and dark” interference fringes. 2. The interference conditions for generating light are: the two light conditions are always the same light source called the coherent light source, only the coherent light source Lights are superimposed on each other to produce interference phenomena. Stable bright and dark phases appear on the screen.
