摘要
The article describes a low-cost experimental apparatus built to simulate and highlight the influence of inertia and elastic properties of matter on the speed of propagation of a mechanical wave. The aim for building this device was to minimize the difficulties associated with the teaching and learning process of physical concepts, particularly in the context of waves. It is about a demonstrative experiment that can be done in classrooms or in a teaching lab.
