   amplitude

   /ˈamplɪtjuːd/

   noun

   • 1. the maximum extent of a vibration or oscillation, measured from the position of equilibrium: "the amplitude of alpha rhythms"
   • ▪ the maximum difference of an alternating electric current or potential from the average value: "the detection of signals only a few microvolts in amplitude"
   • 2. the angular distance of a celestial object from the true east or west point of the horizon at rising or setting.
   • 3. breadth, range, or magnitude: "the amplitude of the crime of manslaughter lies beneath murder"
   • 4. the angle between the real axis of an Argand diagram and a vector representing a complex number.

   Word Origin mid 16th century (in the senses ‘physical extent’ and ‘grandeur’): from Latin amplitudo, from amplus ‘large, abundant’.

   Jun 12, 2024 · Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.

   There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a periodic function is sometimes called the amplitude.

   The maximum magnitude of displacement, so this amount right here, whatever that distance is here, is called the amplitude. So we represent the amplitude with a capital A, and it's called the amplitude, and it's defined to be the maximum magnitude of displacement for that oscillator.
