教材分析《光的反射》选自义务教育课程标准实验教科书《物理》(人教版)八年级上册,是初中物理光学部分的重要内容,反射规律又是初二物理知识的重点。本节课既学习与平面镜、球面镜等有关的原理知识,又是进一步学习光的折射现象的基础,是一节集物理现象、物理概念、物理规律于一体的课,其中光的反射规律是本节课的核心,反射 The “reflection of light” in the teaching material analysis is selected from the eighth grade of the compulsory education curriculum standard experiment textbook “Physics” (PEP). It is an important part of the physical optics of junior middle school, and the law of reflection is the focus of physical knowledge in the second day. This lesson not only learns the basic knowledge related to plane mirrors, spherical mirrors, etc., but also is the basis for further studying the refraction phenomenon of light. It is a lesson in which physical phenomena, physical concepts, and physical laws are integrated into one lesson, in which the law of light reflection is the The core of the lesson, reflection
