    • Abstract

       

      The ‘hypersonic’ velocities for eighteen representative liquids are calculated from the Brillouin displacements in the light scattered by these liquids. The data are compared with those obtained by the ultrasonic method. No detectable dispersion of velocity has been observed in any liquid in going over from the frequency range of 10 MHz in the ultrasonic to 10000 MHz in the hypersonic region.
