Phase Angle

Phase angle is an expression of the displacement between two waves having identical frequencies. There are various ways of defining this. Phase angles are usually expressed as values ∅ such that 0° ≤ ∅ < 360°. In radians, this range is 0  ≤ ∅ < 2π. Once in awhile you will hear about phase angles specified over a range of -180° < ∅ ≤ +180°. In radians, this range is -π < ∅ ≤ +π. Phase angle figures can be defined only for pairs of waves whose frequencies are the same. If the frequencies differ, the phase changes from moment to moment and cannot be denoted as a specific number.
