*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 [[metres]] for [[Mechanical Wave|mechanical waves]], volts [[volt]]s 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]].
