Vibrational Modes of Partly Filled Wine Glasses

Jundt, Gregor; Radu, Adrian; Fort, Emmanuel; Duda, Jan; Vach, Holger; Fletcher, Neville H

Description

Time-average holographic interferometry has been employed to study how the vibrational modes of a singing wine glass change when it is filled with a liquid. While the liquid clearly lowers the resonance frequencies, it does not change the vibrational mode structure in a first approximation. A more detailed analysis, however, reveals that the presence of the liquid causes the simultaneous excitation of two orthogonal modes that are well resolved for the empty glass.
