[[AbsorptionAbsorb (Physics)|Absorbtion]] is the process where [[matter]] takes in [[photonsphoton]]s, particles[[particle]]s, or [[energy]].

*[[AbsorptionAbsorb (Physics)|Absorbtion]] involves the transfer of [[energy]] from the [[Electromagnetic Wave|electromagnetic]] [[wave]] to the material.*It can occur in various forms, such as the [[Absorb (Physics)|absorption]] of [[light]], [[sound]], or other [[radiation]].*[[Material]]s have specific [[absorption Absorption Spectra|absoption spectra]] indicating which [[wavelengthswavelength]] s they [[Absorb (Physics)|absorb]].*[[Absorb (Physics)|Absorbtion]] of [[Visible Light|light]] occurs when the [[energy]] of the [[photon]] is transferred to an [[electron]] in the [[Absorb (Physics)|absorbing]] material.*In [[gas]]es, [[Absorb (Physics)|absorption]] lines in the [[Absorption Spectra|spectrum]] are due to transitions between [[energy]] levels in [[atom]]s or [[molecule]]s.*[[Absorb (Physics)|Absorbtion]] coefficients quantify how much [[Visible Light|light]] is [[Absorb (Physics)|absorbed]] per unit distance in a material.*Applications include [[Absorb (Physics)|absorption]] spectroscopy, which is used to determine the composition of substances. 

*Solar panels [[Absorb (Physics)|absorb]] sunlight to convert it into [[electricity]].*Dark-[[colour]]ed [[object]]s [[Absorb (Physics)|absorb]] more [[Visible Light|visible light]] and therefore [[heat]] up faster than light-[[colour]]ed [[object]]s.
