摘要
探讨在声速测量实验中 ,声波在发射器和接收器两个端面之间反射形成极大值的位置和条件 ,以及声波强度随距离变化的规律 .这有利于学生正确实验和理解声波特性 .
In the experiment of measuring sound velocity,the positions and condition of formed maximum intensity,which is resulted from the sound wave reflected between the ends of the emitter and the receiver,are discussed.The regular pattern of sound intensity,as a function of the distance from the emitter,is researched.It is useful for students to test and understand the properties of sound wave.
