基于matlab仿真的薄透镜焦距测定实验研究

摘要

In the measurement experiment of the thin lens focal length,it is the key thatresearchers choose the experiment conditions correctly. In this paper we intuitively show the law of lens imaging and the relationships between the various physical quantities and the errors in the experiment using MATLAB Numerical simulation. These results can help students enhance the chance of success and deepen the understanding for the student.%薄透镜焦距测定实验中，关于合适实验条件的选择是精确测定焦距的关键环节，利用matlab数值模拟的方法直观的展示了透镜成像规律及实验中各物理量与误差的关系。该结果能够加深学生对实验的理解和把握。
