光的衍射观察难度综合分析

Comprehensive Analysis of the Difficulty in Observation of Light Diffraction

从菲涅耳半波带的处理方法出发,综合分析光源、障碍物、观察点对观察衍射难易的影响,给出共同决定衍射明显与否的几个参量,作为对一些书籍关于衍射明显与否决定于障碍物的线度与光波波长是否可以比拟的简单结论作一个补充.

This paper study the processing method of the Fresnel＇s half-wave belt, and analyse how the light source , stumbling block and observe spot influence the observation of light diffraction and make it different comprehensively. The paper also provide us with some quantities that decide whether it will be obviours in light diffraction. In addition, our study can be a complement that help to disscuss the rash conclution that whether it will be obviours in light diffraction is desided by the light wave wave-lengths of the stumbling block.
