自制的光的反射、折射演示器可用于探究光的反射定律、光的折射定律以及探究光的全反射现象、探究光路是可逆的。该演示器的特点是,功能齐全,利用激光笔的优点,可旋转的旋臂作用,解决了3线共面这一教学难点,使用现象明显,取材简单,制作成本低,造形美观。
Self-made light reflection, refraction of the demonstrator can be used to explore the law of light reflection, light refraction law and explore the total reflection phenomenon of light to explore the optical path is reversible. The demonstrator is characterized by its complete functions, the advantages of a laser pointer, the function of a rotatable spiral arm, and the teaching difficulty of 3-line coplanarity. The utility model has the advantages of obvious application, simple drawing, low production cost and beautiful appearance.
