利用声卡进行水中声速测量

摘要

In this paper,we design an experimental scheme for the measurement of the sound speed in the wa-ter based on the computer sound card. This experiment can be applied to high school physics teaching as de-sign and investigation experiment.%设计了一个基于计算机声卡进行水中声速测量的实验，该实验可以作为设计性和探究性实验应用到高中物理教学当中。
