- How can acoustic resonance reduce the average velocity in a falling body? V. Torres-Zúñiga Física, Astronomía y Matemáticas Resonant tube acoustic pressure high school demonstration In this article, a simple experiment is described to overcome the misconception that acoustic pressure and levitation effects are difficult to observe in school laboratories. Analysis of the free fall velocity of a toy parachute inside a vertical tube, driven by sound in a range of frequencies around the resonant condition, exhibits the resonance frequency, the node pressure zones, and the optimal conditions to obtain acoustical levitation of a light body. 2011 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57024209003 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
