: The [[spectrum]] of [[White Light|white light]] is a continuous change of [[colour]]s with all [[wavelength]]s having the same [[intensity]].
: An '''emission spectrum''' is a set of specific [[wavelength]]s with a high [[intensity]]. This appears as bright lines of [[colour]] on a [[spectrum]].
: A '''emission spectrum''' is created when [[excited]] [[electron]]s ([[electron]]s in high [[Energy Level|energy levels]] ) lose [[energy]] and fall to a lower [[Energy Level|energylevel]] [[emit]]ting a specific [[wavelength]] of light [[electromagnetic Wave|electromagnetic wave]] when they do.
