The wavelength is shorter, with three-fourths λ equaling the length of the tube, so that λ = 4 L / 3 . This higher-frequency vibration is the first overtone. A resonator is a device or system that exhibits resonance or resonant behavior. That is, it naturally oscillates with greater amplitude at some frequencies, called resonant frequencies, than at other frequencies. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce so… chris shulman mediator tampa
