Direct linkDirect link
Fazio, Claudio; Guastella, Ivan; Tarantino, Giovanni – European Journal of Physics, 2009
A problem-based approach to the teaching of mechanical wave propagation, focused on observation and measurement of wave properties in solids and on modelling of these properties, is presented. In particular, some experimental results, originally aimed at measuring the propagation speed of sound waves in metallic rods, are used in order to deepen…
