WebMar 17, 2024 · It has nothing to do with drinking too many beers and getting a beer belly. Named after German mathematician and chemist, August Beer, Beer’s law (or the Beer-Lambert law) observes the linear relationship between absorbance and concentration of a dissolved substance in a solution and is usually expressed as: A = a (λ) * b * c. WebThe Beer–Lambert law relates the absorption of light by a solution to the properties of the solution according to the following equation: A = εbc, where ε is the molar absorptivity of the absorbing species, b is the path length, …
