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 … See more Optical systems can be described with Maxwell's equations, and linear propagating waves such as sound or electron beams have similar wave equations.
