c. Velocity of Ultrasound and Wavelength The velocity of ultrasound (c) in a perfectly elastic material at a given temperature and pressure is constant. The relation between c, f, l and T is given by Equations (2) and (3): Eqn. 2 Eqn. 3 l = Wavelength c = Material Sound Velocity f = Frequency T = Period of time
Ultrasonic velocity is directly connected to the elastic moduli and the density of a solid material. By analyzing ultrasonic shear and longitudinal wave velocities, the Young?s modulus and shear modulus can be determined and by this the Poisson ratio.
