Study on the acoustic resonance in a tube with PASCO sensors

ZHU Li-jun, WEI Xin, YU Ying(Department of Physics, Beijing Normal University, Beijing 100875, China)  
The sound field in a tube is theoretically analyzed from the viewpoint of multiple reflection and experimentally measured with PASCO sensors. The measured resonant curve agrees well with the theoretical prediction, which depends only on the reflection coefficient at the open end of the tube. Based on this fact, the dependence of the reflection coefficient upon the wave frequency is experimentally determined.
