What is Waving and Why? The Anatomy of the Wave Equation – Part 3
By Dr. Eugene Patronis
At the conclusion of the second article in this series we had the plane wave equation in hand and had learned the properties that must be exhibited by a mathematical function if it were to be a solution to the wave equation for a given set of physical circumstances. Now it is time to apply what we have learned towards the study of the wave motion in a plane wave tube that is excited by an oscillating piston as depicted in Fig. 1.
