Parametric instability of a standing gravity-capillary wave is observed when a liquid surface is irradiated by a plane ultrasound beam modulated by amplitude. The threshold value of ultrasound intensity for exciting the parametric oscillations of the surface is determined and the frequency response of the process is measured.
Parametric instability of a standing gravity-capillary wave is observed in conditions of irradiation of a surface of a liquid by a plane ultrasound beam modulated by amplitude. A threshold value of ultrasound intensity for excitation of the parametric oscillations of the surface is determined, and the frequency response of the process is measured. A mechanism of instability based on sound radiation pressure applied to a liquid surface curved with menisci is suggested.
