am·pli·tude

(ăm′plĭ-to͞od′, -tyo͞od′)
n.
1. Greatness of size; magnitude.
2. Fullness; copiousness.
3. Breadth or range, as of intelligence.
4. Astronomy The angular distance along the horizon from true east or west to the intersection of the vertical circle of a celestial body with the horizon.
5. Physics The maximum absolute value of a periodically varying quantity.
6. Mathematics
a. The maximum absolute value of a periodic curve measured along its vertical axis.
b. The angle made with the positive horizontal axis by the vector representation of a complex number.
7. Electronics The maximum absolute value reached by a voltage or current waveform.

[Latin amplitūdō, from amplus, large.]

amplitude

(ˈæmplɪˌtjuːd)
n
1. greatness of extent; magnitude
2. abundance or copiousness
3. breadth or scope, as of the mind
4. (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 body
5. (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 diagram
6. (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.

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.
