British Dictionary definitions for amplitude

amplitude

/ (ˈæmplɪˌtjuːd) /

noun

greatness of extent; magnitude

abundance or copiousness

breadth or scope, as of the mind

astronomy the angular distance along the horizon measured from true east or west to the point of intersection of the vertical circle passing through a celestial body

Also called: argument maths (of a complex number) the angle that the vector representing the complex number makes with the positive real axis. If the point (x, y) has polar coordinates (r, θ), the amplitude of x + i y is θ, that is, arctan y/xCompare modulus (def. 2) See also Argand diagram

physics the maximum variation from the zero or mean value of a periodically varying quantity

Scientific definitions for amplitude

amplitude

[ ăm′plĭ-tōōd′ ]

Physics One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. Compare frequency.

Electronics The amount by which a voltage or current changes from zero or an average value.
