光在两种物质分界面上改变传播方向又返回原来物质中的现象,叫作光的反射.光的反射是初中物理的重要考点,作图题为常见的命题形式.正确作出光的反射光路图是同学们应该掌握的基本技能.一、利用光的反射定律作图光的反射定律内容为:光反射时,反射光线与入射光线、法线在同一平面上;反射光线 Light in the interface between the two substances to change the direction of propagation and return to the original phenomenon in the material, called the light reflection. Light reflection is an important junior middle school physics test sites for the title of a common form of proposition. Correct light reflection light path Figure is the students should master the basic skills First, the use of law of light reflection diagram of the light reflection law as follows: light reflection, the reflected light and incident light, normal in the same plane; reflected light
