基于多功能型分光仪上的创新实验——牛顿环
|
摘要
根据"牛顿环"产生的条件,对多功能型分光仪进行改装、定标,在此基础上搭载牛顿环实验装置.利用该装置测量了平凸透镜的曲率半径R,并对数据进行处理与对比,其实验结果与传统实验十分接近.利用多功能型分光仪搭建牛顿环实验改变了传统实验教学模式,利于学生创新能力的培养.
Based on the conditions to produce Newton rings,a multifunctional spectrometer was refitted and calibrated,and a Newton ring experiment apparatus was setup.Using the improved multifunctional spectrometer,the radius of curvature Rof the spherical surface was measured.Then the experimental data were compared with the theoretical value.The experimental result was quite similar to that of traditional experiment.The innovative device could cultivate students' innovative ability.
