摘要
讨论了薄透镜焦距测量实验中的一些基本问题和主要的系统误差来源,针对教学中容易产生问题的实验现象给出了重点分析.利用目镜分划板系统代替传统像屏能准确确定像平面位置,并以此为基础设计了综合性实验.
Some basic problems in the experiment of focal length measurement of thin lens was discussed,the main sources of systematic errors and the experimental phenomena that confused the students were analyzed.In this experiment,the eyepiece reticle system was used instead of the traditional image screen to confirm the image plane.Based on this,a comprehensive experiment was designed.
