Solution of eikonal equation
WebThe eikonal approximation, a partial solution of the wave equation relevant to seismic processing, may be derived by manipulation of these diagrams. In fact, the diagram derivation achieves its goal in an arguably less roundabout way than other, superficially more elegant, perturbation methods.
