摘要
用分光计测量三棱镜顶角时,入射光是否垂直于三棱镜底边,对测量结果均无影响,因此实验中不必强调入射光的垂直度问题。然而在用分光计测量光栅常数时,入射光必须垂直入射到光栅平面上,否则将会对测量结果产生误差。本文将对以上问题进行理论分析及指导实验的操作。
When the spectrometer is used to measure the vertical angles of a prism,the results are not affected whether the ray of recidence is vertical to the bottom side of the prism or not.However,in the case of measuring the grating constant by a spectrometer,the light of incidence should be vertical to the plane of grating to ensure the accuracy of measurement. This paper analyzes the above problems theoretically and provides instructions for experiments.
