光的衍射和漫反射现象教学创新与拓展

Teaching Innovation and Development of Diffraction and Diffuse Phenomena of Light

在大学物理教学中,光的衍射现象和漫反射效应是必备的知识点。在理想条件下,夫琅禾费单缝衍射中会有衍射光芒并带有明暗相间条纹的出现,有色粉末的研磨程度越高,漫反射越强,颜色越深。把光的衍射现象和漫反射效应的演示带入课堂,引导学生对影响现象的因素进行探讨,并给出合理的解释。

In the teaching of college physics,the diffraction phenomenon and diffuse reflection effect are essential knowledge points.Under ideal conditions,Fraunhofer's single slit diffraction will have diffraction light with light and dark stripes;the higher the grinding degree of the colored powder,the stronger the diffuse reflection and the darker the color. The demonstration of light diffraction and diffuse reflection effect is brought into the classroom to guide students to explore the factors affecting the phenomenon and give reasonable explanations.
