: 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|energy level]] [[emit]]ting a specific [[wavelength]] of [[electromagnetic Wave|electromagnetic wave]] when they do.

| style="height:20px; width:200px; text-align:center;" |This [[diagram]] shows an [[excited]] [[electron]] losing [[energy]] by [[emit]]ting an [[Electromagnetic Wave|electromagnetic wave]]. As it does this the [[electron]] falls back down to a lower [[Energy Level|energy level]].
