===Meaning===
[[Absorb (Physics)|Absorbtion]] is the process where [[matter]] takes in [[photon]]s, [[particle]]s, or [[energy]].
===About Absorption===
*[[Absorb (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 Spectra|absoption spectra]] indicating which [[wavelength]]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.
===Examples===
*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.
