Phase-Shift

The displacement of a Waveform in time. For example, if a waveform is displaced by a complete Wavelength it is described as having a phase-shift of 360°. If it is displaced by half a wavelength (i.e. 180°) one wave will peak where the other is in a trough state and complete Cancellation will result. If they are at any other angle of phase-shift, partial cancellation will result.
