作图题是光学中常见的基本题型,它能直观、形象地反映出物理过程和物理问题的本质,有助于我们对物理问题的深入理解.光的反射和光的折射作图是光学作图的基础,解决此类问题的关键是理解和掌握光的反射定律和光的折射规律的内涵,并且要学会利用几何知识进行绘图,这样便可以攻克光学作图的堡垒.下面以近两年的中考题为例,展示解决的方法. Drawing questions are common basic questions in optics, which can intuitively and vividly reflect the essence of physical processes and physical problems, and help us to understand the physical problems deeply. Light reflection and light refraction mapping are optical The basis of the figure, the key to solve such problems is to understand and grasp the light reflection law and the light refraction of the connotation, and to learn to use the geometry of knowledge mapping, so that you can overcome the optical mapping of the fortress. As an example, show how to solve it.
