摘要:

We investigate the role of a classroom torsional wave machine as a science prop and teaching aid, having already considered the physics behinds its design and operation in a companion article last month. We now present a selection of experiments designed to compare theory with experiment, demonstrate basic wave phenomena, and introduce fascinating concepts such as cut-off frequency and dispersion.
