目前教材中对干涉条纹移动问题讨论的大多是光线垂直入射时的情况,对光线斜入射的情况讨论极少。本文通过杨氏干涉实验中,光线斜入射时对狭缝前(或后)盖介质片等几种情况下,屏上干涉条纹移动的原因和方式进行分析,寻求条纹移动的规律,并与正入射时得出的结论进行对比,得出总体的规律,找到一种快速、简便处理条纹移动问题的途径。
目前教材中對榦涉條紋移動問題討論的大多是光線垂直入射時的情況,對光線斜入射的情況討論極少。本文通過楊氏榦涉實驗中,光線斜入射時對狹縫前(或後)蓋介質片等幾種情況下,屏上榦涉條紋移動的原因和方式進行分析,尋求條紋移動的規律,併與正入射時得齣的結論進行對比,得齣總體的規律,找到一種快速、簡便處理條紋移動問題的途徑。

The current textbooks are more focused on the light vertical incidence, less on the light oblique incidence. Based on Young's double-slit interfering experiment, this paper analyses the reasons and ways of interference fringes moving on screen When light is slanting, and tries to find out the stripe moving regularity. Then compared with the conclusion drawn on the basis of normal incidence, the paper tries to conclude the general rule so that a quick and simple way to solving fringe shift problems can be found out.
