自制光的全反射演示仪

摘要

利用全反射原理，通过改变光疏介质的折射率，使全反射条件在满足与不满足之间转换，进而可使2条主要的出射光线颜色互换，实验现象直观，具有趣味性。%A demonstrated device for total reflection was made .The total reflection condition was satisfied by adjusting the refractive index of optically thinner medium .Using this device ,the color of the two outgoing light beam could be exchanged ,which was intuitive and interesting .
