Abstract

In this project we find the speed of one longitudinal and two transverse plane harmonic waves propagating in the same direction but polarizing along different directions mutually orthogonal to each other, in homogeneous and non-homogeneous orthorhombic materials. We calculated these speeds in two specimen, viz, Iodic Acid and Barium Sodium Niobate, of the said materials. From the experiments we observe that non-homogeniety of the material increases the speed of these waves.
