amplitude (ăm`plĭt
d'), in physics, maximum displacement from a zero value or rest position. In the harmonic motion harmonic motion, regular vibration in which the acceleration of the vibrating object is directly proportional to the displacement of the object from its equilibrium position but oppositely directed.

Amplitude is important in the description of a wave wave, in physics, the transfer of energy by the regular vibration , or oscillatory motion, either of some material medium or by the variation in magnitude of the field vectors of an electromagnetic field (see electromagnetic radiation ).

amplitude
The strength or volume of a signal, usually measured in decibels. See wavelength.

| The amplitude is the power of a signal. The greater the amplitude, the greater the energy carried. |
amplitude
1. 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
2. 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 + iy is θ, that is, arctan y/x
3. Physics the maximum variation from the zero or mean value of a periodically varying quantity
