| 摘 要： | 薄膜干涉是一种常见、有用的干涉效应。现行大学物理教材中只讨论了光场的强度效应而忽略了频率效应。该文从相位差与光程差的关系出发，得到了干涉场中光强随光波频率(波长)的分布，结合具体实例，给出了归一化的光强(反射光与透射光)随波长变化的关系曲线。

| Abstract: | Thin film interference is one of general and available interference phenomena. Only the intensity effect of optical field is discussed,and frequency effect is ignored in college physics teaching material.In this paper, the dis-tribution of optical intensity in the interference field vs frequency is obtained according to the relation between phase difference and optical length difference, combined with an example the normalized optical intensity ( reflective light and transmission light)is givern.This paper can be as a good cornplenmentarity of teaching material. |
