三棱镜是常见的光学器具,可以改变光的传播方向,发生光的色散现象.在光学中有很多与三棱镜有关的习题,这些问题涉及到光的反射定律、折射定律、全反射及色散等方面的知识运用.下面就常见的有关三棱镜的典型问题进行归类分析. 一、光线在棱镜内的光路分析 Prism is a common optical device that can change the direction of light propagation, resulting in the phenomenon of light dispersion. There are many problems related to prisms in optics. These problems involve the law of light reflection, the law of refraction, total reflection and dispersion, etc. The use of knowledge. The following is a common analysis of the typical problems related to the prism. First, the light path analysis in the prism
