Resonance Tube


Quick Overview

Equipment developed for resonance experiments in open tube and closed tube. With it you can determine the speed of sound in air with great accuracy.
Experiments can be performed visually using the cork dust to show nodes and wombs of the standing wave or use the microphone.
With the microphone you can find the nodes and wombs of the standing wave by using the function generator.
Furthermore, by using an oscilloscope, it is possible to visualize the appearance of the standing wave inside the tube, that is captured by the microphone and thereby get a result also more accurate.
