==Key Stage 4==
===Meaning===
[[File:FlameEmissionSpectroscopy.png|right|300px|thumb|The [[Emission Spectrum|emission spectra]] from the of several [[metal]]s.]]
'''Emission spectra''' are the specific [[wavelength]]s of [[light]] [[emit]]ted by the [[electron]]s in [[atom]]s as they lose [[energy]].
===About Emission Spectra===
: 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 [[electron]]s in high [[Energy Level|energy levels]] lose [[energy]] and fall to a lower [[energy]] [[emit]]ting a specific [[wavelength]] of light when they do.
