基于手机APP实现驻波法对声速的测量

摘要

介绍了一种利用普通智能手机和一根两端开口奶茶管基于声驻波现象来测量声速的方法.这种实验方法所用的实验仪器随手可得,无需学生再到学校的实验室进行实验,激发了学生的学习兴趣,增强了学生的动手能力.%It introduces a method to measure the sound speed by using just two smart phones and a common milk tea tube based on the principle of standing wave.For these instruments are readily available,we needn't to go to the school laboratory.It inspires the students' learning interest and enhances their practical ability.
