Sound Wave 2
Sound Wave 2 : Also called: acoustic wave, sonic wave: A mechanical disturbance advancing with finite velocity through an elastic medium and consisting of longitudinal displacements of the ultimate particles of the medium, i.e., consisting of compressional and rarefactional displacements parallel to the direction of advance of the disturbance; a longitudinal wave. Sound waves are small-amplitude adiabatic oscillations. The wave equation governing the motion of sound waves has the form: c2 dt1 where V2 is the Laplace operator,
