摘要
分析了非单色点光源杨氏双缝实验中屏上出现衬比度为零的区域的原因.从以光程差定义的衬比度为零和波列长度小于光程差使波列不相重叠两个角度进行了解释.
Certain areas of the pattern show zero contrast in the Young＇s double slit experiment with a nonmonochromatic point source. Two theoretical explanations are proposed here, with one applying the contrast defined by optical path difference and another indicating it is due to wave trains cannot overlap when the length of them is less than the optical path difference.
