El experimento de Michelson y Morley en versión acústica, un trabajo de laboratorio de física universitaria basado en aprendizaje por indagación

: is article presents a didactic activity developed in the university classroom within the framework of Inquiry-Based Learning. In this activity, students of the faculty and the degree in physical sciences generated new questions and hypotheses using an experimental design already built: an ultrasound acoustic interferometer. e results of two groups of students who took the device and modified its original design are shown. is work summarizes the theoretical and methodological resources used in wave physics laboratory classes with low-cost materials. It was also taken into account in the design of this activity to train students in the skills of their career.
