The One-Dimensional Wave Equation

Abstract

Earlier we talked about the waves on a pond. Before we start looking specifically at sound waves, let's review some general information about waves. Types There are two general classifications of waves, longitudinal and transverse: Transverse Wave – A traveling wave in which the particles of the disturbed medium move perpendicularly to the wave velocity. An example is the wave pulse on a stretched rope that occurs when the rope is moved quickly up and down. Longitudinal Wave – A traveling wave in which the particles of the medium undergo displacement parallel to the direction of the wave motion. Sound waves are longitudinal waves.
