A home-lab experiment: resonance and sound speed using telescopic vacuum cleaner pipes

Abstract
We propose a home laboratory in which a telescopic vacuum cleaner pipe and a smartphone are used to investigate sound speed and acoustic resonance. When the pipe is hit or the hands clapped near one end the sound produced is registered by a smartphone. By means of an appropriate application the resonant frequency is obtained. Varying the pipe's length and registering the corresponding resonant frequency allows to obtain the sound speed. This home-lab, first proposed during covid19 pandemic, has been incorporated as a home challenge to experiment with acoustic resonance in new normal times.
