Mechanical Wave Driver and Resonance on A Circular Wire
Demo Description
A mechanical driver powered by an acoustical speaker cone and a function generator is used to excite standing waves on a circular loop of stiff wire
Scientific Principles
Standing waves on a circular wire may be used to motivate the notion of wave-particle duality.
