双缝干涉实验再研究

Restudy on Double Slit Interference Experiment

由于中学阶段学生所学知识有限、数学能力不足,大多数教材只是用近似条件简单地分析了干涉条纹等间距分布,不仅未细说为何可以作这样的近似处理,也并未对实验中的某些现象作出解释说明,造成部分学生较大的困惑.现利用不同方法处理,借助C++程序,直观地解释了这些中学阶段没能解释的现象.

Due to the limited knowledge and mathematical ability of high school students,most course books only use approximate conditions to analyze the equal spacing distribution of interference fringes.It does not explain in detail why such an approximate treatment can be made,nor does it explain some phenomena in the experiment,which may bring great confusion to students.In this paper,with the assistance of C++program,we adopt different methods to deal with them and explain these phenomena intuitively,which can not be explained during high school studying.
