Web5 mrt. 2024 · Let a world-line of propagation of the wave lie along the vector → v. In the case of a wave propagating at c, we have v2 = 0 (so that → v can’t have the usual normalization for a velocity vector), and the dispersion relation is simply ω2 = 0. Since the phase stays constant along a world-line of propagation, ω → v = 0. goopc hcts https://djbazz.net
