摘要
介绍一种利用全反射原理测定水的折射率的方法 ,实验中利用He -Ne激光束在水底产生点光源 ,根据全反射原理对水底的暗影和水深进行测量 。
The experiment method of measuring refractive index of water by using total reflection principle is improved. In the experiment to bring shot lamp-house by laser bean in the bottom of water. The depth of water and the shadow of water bottom were measured by using total reflection principle.The refractive index of water was figured out.
