About this document
Displacement and Pressure Waves Explained by veda is a document available to read on EtoBox.
The document discusses displacement and pressure waves. A longitudinal sound wave can be expressed as either a displacement wave using the equation y = Asin (wt - kx) or a pressure wave. The pressure wave is derived from the displacement wave and is represented by the equation P = PoCos(wt - kx) where Po = ABk. The pressure wave is π/2 out of phase with the displacement wave, with pressure maximum when displacement is minimum.
