光的全反射现象在自然界中很常见又有着很多应用,但光路的不易视性给学生接受这种自然现象和掌握全反射规律带来了困难。做好全反射的演示实验或辅助实验,使光路可见成为化解难点的有效手段。
The phenomenon of total reflection of light is common and has many applications in nature. However, the invisibility of light path makes it difficult for students to accept this natural phenomenon and grasp the law of total reflection. Do full reflection of the demonstration experiment or auxiliary experiment, the optical path visible as an effective means to resolve difficulties.
