WebIn physics, the wavefront of a time-varying wave field is the set of all points having the same phase. The term is generally meaningful only for fields that, at each point, vary sinusoidally in time with a single temporal frequency (otherwise the phase is not well defined).. Wavefronts usually move with time. For waves propagating in a …
