*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., [[metre]]s for [[Mechanical Wave|mechanical waves]], [[volt]]s for electrical signals).
*In a [[sound wave]], [[amplitude]] determines the loudness.
*In a [[Visible Light|light wave]], [[amplitude]] affects the brightness.
*[[Amplitude]] can be affected by damping, which reduces the [[amplitude]] over [[time]].
*In [[simple harmonic motion]], [[amplitude]] remains constant if no [[energy]] is lost.
*[[Amplitude]] modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a [[radio]] carrier wave.
