===Meaning===
[[File:AbsorptionSpectra.png|right|300px|thumb|The [[Absorption Spectra|absorption spectra]] of several [[metal]]s.]]
'''Absorption spectra''' are the specific [[wavelength]]s of [[light]] [[Absorb (Physics)|absorbed]] by the [[electron]]s in [[atom]]s as they gain [[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 '''absorption spectrum''' is a set of specific [[wavelength]]s with a low [[intensity]]. This appears as dark lines of of missing [[colour]] from the normal [[spectrum]] made by [[White Light|white light]].
: A '''absorption spectrum''' is created when [[electron]]s [[Absorb (Physics)|absorb]] the [[energy]] from an [[electromagnetic Wave|electromagnetic wave]] and jump to a higher [[Energy Level|energy level]] in an [[atom]]. This removes that particular [[wavelength]] of [[electromagnetic Wave|electromagnetic wave]] [[White Light|white light]] being [[transmission|transmitted]] or [[reflection|reflected]] from that [[material]].
: The [[wavelength]]s of [[electromagnetic Wave|electromagnetic wave]] depend on the [[energy]] difference between the [[Energy Level|energy levels]] in [[atom]]s.
