摘要
介绍了2个有趣的测量声速的实验:在室内,采用驻波法结合电脑来测量声速;在室外,利用不同的传播途径结合电脑来测量声速.2个实验可以让学生直接参与实验操作,激发了学生学习的兴趣.
Two interesting experiments of measuring sound speed were introduced. In the first indoor experiment, the sound speed was measured with computer-aided standing wave method in the second outdoor experiment, the sound speed was measured with different routes of transmission assisted by computer. The practice showed that the two experiments were interesting and feasible, and students could join in both of two experiments. It stimulated students＇ interests in learning.
