Acoustic impedance and sound velocity for different materials - Data from Alan Selfridgae.
After a definition of ultrasound, the wave equation and sound velocity relevant to fluids are derived. For solids, the wave equation and elastic properties lead to the propagation of shear waves as well as longitudinal waves.
... f is the ultrasonic frequency Table 1 lists typical values of the sound velocity c for various materials. ...
