The Mechanism Of The Interference Film On the Optical Lens

文章从矢量叠加的“零效果”与无矢量叠加的“零结果”概念区别入手,提出机械波干涉现象产生的本质是介质中能量的重新分布。介绍了电磁波在介质中干涉的几种不同的理论解释,最后提出了在中学物理教学中如何避开教材知识狭隘、结构单一局限,结合中学生感性思维特点,深入浅出地阐述了增透膜增透机理。

From the defference between vector superposition's nonresult and no vector superposition's zero result, a viewpoint is given that the essence Of the machine wave interference is energy resettled in medium. All so, Different theories about the interference of electromagnetic waves in medium are introduced. Finally, it is put forward how to keep away from the localization of the teaching material in middle school and how to explain the profound principles of interference film in simple way.
