The wave equa-tion is a second-order linear hyperbolic PDE that describesthe propagation of a variety of waves, such as sound or water waves. It arises in different fields such as acoustics, electromagnetics, or fluid dynamics. In its simp lest form, the wave ...

(Say, the KdV equation, or the paraxial wave equation for the propagation of light in a graded-index optical fiber (a.k.a. the Schrödinger equation).) The notation is somewhat unfortunate (so perhaps 'the' wave equation should have a better name), but it is what it is ... WebThe previous equation is a first-order PDE. ... Hence the wave equation (or any hyperbolic PDE) has two families of real characteristic curves. If initial conditions are specified for the wave equation, the solution propagates along the characteristic lines. Also, any fixed pair of characteristic lines determine the null cone of an observer ... indiana open container law
