Noun
wave equation (plural wave equations)
A second-order linear partial differential equation for the description of waves or standing wave fields.
A more general representation of the wave equation is more complex, but the role of amplitude remains analogous to this simple case. Source: Internet
Although the word "monochromatic" is not exactly accurate since it refers to light or electromagnetic radiation with well-defined frequency, the spirit is to discover the eigenmode of the wave equation in three-dimensions. Source: Internet
Both types of waves can have a waveform which is an arbitrary time function (so long as it is sufficiently differentiable to conform to the wave equation). Source: Internet
General aperture The wave that emerges from a point source has amplitude at location r that is given by the solution of the frequency domain wave equation for a point source (The Helmholtz Equation ), : where is the 3-dimensional delta function. Source: Internet
An observation or measurement of an object by an observer is modeled by applying the wave equation to the entire system comprising the observer and the object. Source: Internet
A solution of the initial-value problem for the wave equation in three space dimensions can be obtained from the corresponding solution for a spherical wave. Source: Internet
