摘　　要：基于光子动量在不同媒质分界面上沿分界面方向守恒原理,制作了光的折射定律演示装置.使用该装置可演示入射角连续变化,折射角也自动遵循折射定律相应变化.本文介绍了该演示装置的原理、构造及使用方法.Based on the conservation of photon momentum component parallel to the interface, the demonstration device of refraction law of light is made. This device can demonstrate that the deflection angle changes with the incident angle according to the Snell law. This paper introduces the principle and structure of the device, and how to use it.

关 键 词：折射定律 光子动量 守恒原理
