摘要
F-P干涉仪测Na灯的波长差是大学普通物理实验中一个重要的实验内容,但是做实验的学生多是没有光学专业知识背景的理工科学生,对实验原理的理解存在一定的困难.文章通过几个简单问题的提出及回答清晰阐述了F-P干涉仪测Na灯波长差的实验原理,加深了学生对实验的理解,提高了实验操作的成功率及物理实验的教学质量.
Measuring wavelength difference of Na light source with Fabry-Perot （F-P） inter- ferometer is an important college general physics experiment. However, the principle of this experiment is pretty difficult to be understood by college students majoring natural science other than optics, who usually have weak background optical knowledge. In view of the above problem, the present article clearly explains the experiment principle of the F-P interferometer by providing several simple questions and corresponding answers, which improves the students＇ understanding of the experiment, increases the probability of experimental operation sueeess, and enhances the teaching quality of this experiment.
