有关平面镜成像的习题较多,但不管是什么样的题目,在解答时都应注意平面镜成像规律的灵活运用,成像规律有以下几点:①物与像关于平面镜对称;②入射光线、反射光线及对应法线在同一平面内;③入射角等于反射角;④反射光线的延长线必过像点。下面对平面镜成像作图题分类说明。
There are many exercises related to plane mirror imaging, but no matter what kind of problem, we should pay attention to the flexible use of the law of plane mirror imaging in the solution. The following laws are applicable to the imaging law: 1 The object and the image are symmetrical about the plane mirror; 2 The incident light and the reflected light And the corresponding normals are in the same plane; 3 the incident angle is equal to the reflection angle; 4 the extension of the reflected light must pass through the image point. The classification description of the imaging problem of plane mirror is explained below.
