普通物理实验中使用分光计观察白光散射,测量三棱镜顶角,最小偏向角等。但在测量前需借助三棱镜调整分光计,有人通过理论分析发现传统的调节方法存在误调和误差,并提出了改进的实验调整方法。本文我们通过实验来验证该方法是否可行,并在实验中发现了其它的问题。 Common physical experiments using a spectrometer observed white light scattering, prism angle measurement, the minimum deflection angle. However, before the measurement, the prism needs to be adjusted by using a prism. Some people find that there are errors and errors in the traditional adjustment methods through theoretical analysis, and propose an improved experimental adjustment method. In this paper, we experiment to verify the feasibility of this method, and in the experiment found other problems.
