What is Beer-Lambert law?
{{no sources|date=March 2018}} [[File:Beer–Lambert law in solution.JPG|thumb|A demonstration of the Beer–Lambert law: green laser light in a solution of [[Rhodamine B|Rhodamine 6B]]. The beam becomes weaker as it passes through solution.]] The '''Beer–Lambert law''', also known as '''Beer's law''', the '''Lambert–Beer law''', or the '''Beer–Lambert–Bouguer law''' is a [[science|scientific]] [[law]]. It deals with the [[absorption]] of [[light]] moving through a [[material]]. The law is commonly used with [[chemical analysis]] measurements. It is used in understanding [[attenuation]] in [[physical optics]], for [[photons]], or [[neutrons]]. In [[mathematical physics]], this law is a solution of the [[Bhatnagar–Gross–Krook operator|BGK equation]]. == References == {{reflist}} {{Physics-stub}} [[Category:Laws of physics]] [[Category:Optics]] [[Category:Color]]
