Summary/Abstract: An experimental setup for measuring the speed of sound in air is described. The experiment can be reproduced with readily available tools, in any school. A smartphone was used, running tone generating apps available for free along with a digital oscilloscope. A sound frequency is assigned using the tone generator and is reproduced by the smartphone’s loudspeaker and is further observed using the digital oscilloscope. A pipe is used as a resonator, and by dipping one end in water the air column length is adjusted. Some of the systematic effects leading to error in results are researched and evaluated.
