“声光衍射与液体中声速的测定”实验改进探析

摘要

We explored the experiment of ‘acousto-optic diffraction and Measurement of Velocity of Sound in liquid’ ,and an experimental device for measuring the diffraction spot center was designed and assembled. The device reduces the error which was caused by the traditional experimental method in measurement of the spot distance,the improved measurement method is simple,and the results are accurate.%本文在分析“声光衍射与液体中声速的测定”实验原理的基础上，提出了实验改进方法，组装了一套简单可行的测量衍射光斑中心位置的实验装置，从而减小了传统实验方法中测量光斑间距的误差，提高了实验精度。
