Plane Harmonic Elastic Waves in Homogeneous and Non-Homogeneous Isotropic Material

This article deals with the speed of two plane elastic waves namely, longitudinal and transverse waves which are propagating in homogeneous and non-homogeneous isotropic material. Inorder to calculate the speed of waves, four specimens viz, aluminium, gold, platinum and silica of homogeneous and non-homogeneous isotropic materials are used and then the speed with different velocity for the four specimen is finally compared.
