Webb22 jan. 2024 · According to Huygens principle of wave theory, the future position of the wavefront may be derived from a past position by considering every point of the wavefront to be a source of secondary waves. The progress of the wavefront can often be described by ray optics. We now turn to situations where rays provide totally inadequate description. In physics, the wavefront of a time-varying wave field is the set (locus) 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 unidimensional medium, …
