Changes

*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 [[Visible Light|light wave]], [[amplitude]] affects the brightness.

*[[Amplitude]] can be affected by damping, which reduces the [[amplitude]] over [[time]].

*In [[Simple Harmonic Motion|simple harmonic motion (SHM)]], [[amplitude]] remains constant if no [[energy]] is lost.

*[[Amplitude Modulation|'''Amplitude''' modulation (AM)]] is a technique used in electronic communication, most commonly for transmitting information via a [[radio]] [[Carrier Wave|carrier wave]].
