    • Abstract


      A numerical estimation of the angles between wave-normal and vibration direction of the elastic waves for various classes of crystal has been given. The anisotropy in elastic wave propagation is strikingly manifested by the crystal Ammonium di-hydrogen phosphate belonging to the tetragonal system, which shows a maximum inclination of thirty-four degrees. Numerical studies have also been carried out for this crystal to obtain an estimate of the deviation of the ray vector from the direction of the wavenormal.
