Is there a formula for determining local particle displacement caused by ultrasonic vibration in a medium? I would suspect that the displacement is proportional to the displacement of the transducer but it should be more difficult to cause cause displacement in solids than liquids. Also, are the transverse particle displacements caused by mode conversion from compression mode to transverse mode of an amplitude equal to that of the compression mode? Is this dependent on the incident angle (above or below critical angle)?
