摘要
基于通过对现有实验项目的改造,在大学物理实验中开出研究性实验.本文选用菲涅耳双棱镜干涉实验,选择提高测量精度的思路,对影响实验测量精度的因素进行深入地分析,学生借助已学知识研究改善实验精度的措施.结果表明:光源线度、光束光强比和光源和棱镜间距必须恰当调整才能准确测量光波波长.
Research experiments are created by improving the existing facilities. In order to improve the precision of the Fresnel biprisms interference experiment, the students are guided to analyze the influencing factors and to explorer measures to improve accuracy with the knowledge known. It is suggested by studies that the size of light source, intensity ratio of two beams and the distance between prisms should be appropriately adjusted to improve accuracy.
