PPT-Slowness vector and ray velocity

magnitude from ray direction in TTI media Igor Ravve and Zvi Koren Emerson Forward Problem Given the spatial elastic tensor components and the slowness vector direction of a specific wave type compute the ray velocity vector . Wave equations. What is a wave?. what is a wave?. anything that moves. This idea has guided my research: . for matter, just as much as for radiation, in particular light, we must introduce at one and the same time the corpuscle concept and wave concept. .
