平面镜成像的目域及视场问题既是高中几何光学的重要内容也是学习中的难点。教学实践表明,理解掌握平面镜成像的规律是解决这两类问题的基础,总结归纳其解题思路是求解的关键。1 平面镜成像的基本规律平面镜成像的基本原理是光的反射定律,它揭示的是一面(反射镜面)、两角(入射角和反射角)和三线(入射光线、反射光线、法线)的关系,物体经平
The problem of the field of view and the field of view of planar mirror imaging is not only an important content of high school geometry optics, but also a difficult point in learning. Teaching practice shows that understanding and mastering the law of plane mirror imaging is the basis for solving these two types of problems, and summarizing and summarizing the problem solving ideas is the key to solving. 1 Fundamental laws of plane mirror imaging The basic principle of plane mirror imaging is the law of light reflection. It reveals the relationship between one side (mirror surface), two corners (incident angle and reflection angle), and three lines (incident light, reflected light, and normal line). Object level
