最小偏向角测定折射率实验改进

Improvement of the Method of Measuring Refractive Index Yang Hui Jianzai he

大学物理光学实验中,用分光计测量最小偏向角时,往往找到的是一个微小范围内的值,不能精准确定最小偏向角,针对这一问题,文章给出了相应的解决办法,即用两块薄铁片确定入射光与反射光的水平程度来精准确定最小偏向角,改进后的实验用时减少,实验数据准确度大幅度提高.

In college physics experiment,when measuring the minimum angle of deviation with spectrometer,it is often found in a small range of values and wecan not accurately determine the minimum angle of deviation.In view of this problem,the corresponding solution isgiven:the minimum angle of deviation is accurately determined by determining the level of the incident light and the reflected light by two thin iron sheets.After the improvement,the experimental time is reducedand the error of manual calculation is eliminated.
