amplitude

(ˈæmplɪˌtjuːd) n1. greatness of extent; magnitude2. abundance or copiousness3. breadth or scope, as of the mind4. (Astronomy) 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 body5. (Mathematics) maths Also called: argument (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 + iy is θ, that is, arctan y/x. Compare modulus² See also Argand diagram6. (General Physics) physics the maximum variation from the zero or mean value of a periodically varying quantity[C16: from Latin amplitūdō breadth, from amplus spacious]

am•pli•tude

(ˈæm plɪˌtud, -ˌtyud)

n. 1. the state or quality of being ample, esp. as to breadth or width; largeness. 2. large or full measure; abundance. 3. mental range, scope, or capacity. 4. the absolute value of the maximum displacement from a zero value during one period of an oscillation. 5. the maximum deviation of an alternating current from its average value. 6. the arc of the horizon measured from the east or west point to the point where a vertical circle through a heavenly body would intersect the horizon. 7. argument (def. 8b). [1540–50; < Latin amplitūdō. See ample, -i-, -tude]

am·pli·tude

(ăm′plĭ-to͞od′) One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave, for example, 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°. See more at wave.

amplitude

A wave’s greatest displacement from equilibrium.
