Abstract
The study of the behavior of a standing wave inside a resonant cavity, such as a closed tube, has always been of great revelation in the manufacture of wind musical instruments, in addition to research carried out on the transfer and absorption of heat, energy and pressure for the acoustic characterization of materials by injecting sound waves at one end of the Kundt?s tube. In this work, we did the implementation of two experiments for measure the speed of sound, using a Kundt?s tube where also we obtained the bellies and nodes of the sound wave and we verified with a computational code that was written for us in Python, in which we made simulation of the temporal evolution was achieved of the wave that vibrated inside the tube. Also, we show the wave profile for the first four harmonics with computational simulations and we presented the experimental results by two different methods, these were compared with the obtained using the equations modeled by the undulatory theory of physics. Finally, we show in this article, the respective errors obtained from these two experimental configurations, which were made with the purpose of showing university students the importance of being able to visualize the wave phenomenon of sound inside a Kundt?s tube.(Kundt's tube, resonant cavity, harmonics, stationary waves, fundamental frequency.)
