This project proposes the analysis of the phenomenon of standing waves in open and closed tubes used to this, two smartphones and mini bluetooth speaker. Applications waveform generator and spectrum analyzer developed under the Android operating system used. The results of harmonic number n frequency plotted, obtaining a good correlation of data, calculating the slopes of straight lines, resulting in the speed of sound in air of 336.64 m/s 340.4 m/s for open and closed tubes respectively.

Palavras-chave : Signal generator; spectrum analyzer; standing waves in open tubes; standing waves in closed tubes.
