In the context of vectors and phasors, the term phase angle refers to the angular component of the polar coordinate representation. The notation for a vector with magnitude (or amplitude) A and phase angle θ, is called angle notation.
In the context of periodic phenomena, such as a wave, phase angle is synonymous with phase.
Famous quotes containing the words phase and/or angle:
“The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.”
—W.E.B. (William Edward Burghardt)
“It is a mistake, to think the same thing affects both sight and touch. If the same angle or square, which is the object of touch, be also the object of vision, what should hinder the blind man, at first sight, from knowing it?”
—George Berkeley (1685–1753)
