摘要
本文用复数法推导出了多光束干涉的光强公式,并由公式得出了干涉主极大、次极大、极小值的条件。
This Paper deduces the formual of luminous intensity of the interference to light beams with complex numbers . Through the formula , conditions of interference to maximum , sub-maximum and minimum are obtained .Explanation with examples is at the end .
