Objective: Determine the speeds of sound propagated by longitudinal and transverse waves in solids

In solids, sound is propagated in the form of longitudinal and transverse waves. However, there is a considerable difference in the speed of the two types of sound waves, since longitudinal sound waves are determined by the elastic modulus of the solid, whereas transverse sound waves are dependent on the shear modulus of the solid. By measuring the speed of the two wave types, it is possible to determine the elastic constant of the solid.
