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)
“I fly in dreams, I know it is my privilege, I do not recall a single situation in dreams when I was unable to fly. To execute every sort of curve and angle with a light impulse, a flying mathematics—that is so distinct a happiness that it has permanently suffused my basic sense of happiness.”
—Friedrich Nietzsche (1844–1900)
