==Key Stage 5==
===Meaning===
[[Amplitude]] is the maximum [[displacement]] from [[equilibrium]] in an [[oscillating]] [[system]].
===About Amplitude===
*Measures the strength or [[intensity]] of a [[wave]].
*Larger [[amplitude]] means more [[energy]] is carried by the wave.
*Can be [[measure]]d in various units depending on the type of [[wave]] (e.g., meters for mechanical waves, volts for electrical signals).
===Examples===
*The loudness of a [[sound]] is related to the [[amplitude]] of the [[sound]] wave.
*The brightness of a [[Visible Light|light]] [[wave]] increases with its [[amplitude]].
