===Wave interference=== {{Main|Interference (wave propagation)}} The phenomenon of [[Interference (wave propagation)|interference]] between waves is based on this idea. When two or more waves traverse the same space, the net amplitude at each point is the sum of the amplitudes of the individual waves. In some cases, such as in [[noise-canceling headphones]], the summed variation has a smaller [[amplitude]] than the component variations; this is called ''destructive interference''. In other cases, such as in a [[line array]], the summed variation will have a bigger amplitude than any of the components individually; this is called ''constructive interference''.
