驻波法测声速原理教学的讨论

Discussion on the Teaching of the Measurement of Sound Velocity with Standing Wave Method

针对驻波法测声速实验,本文说明了现行教材中原理阐释的不完善之处,并基于大学物理的基础理论知识,从驻波共振的角度出发,以清晰简明的方式重新梳理实验原理,使学生对此实验原理有更清楚的认识。

In response to the experiment of the measurement of sound velocity using standing wave method, the imperfections of the explanation of principle in current teaching materials are explained. The experimental principle is rearranged in a clear and concise way so that students have a clearer un derstanding of the experimental principle.
