Critical angle of refraction - semi-circular cylindrical mobile light source, the incident angle change the size of refraction angle to change at this time, when the refraction angle = 90 degrees, which is critical at this time angle of incidence angle, the critical angle of water at 40 degrees large about anything mobile source of water in the water screen that is a reflection of light, a phenomenon that total reflection.

光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。
