Beer law

(bēr),
the intensity of a color or of a light ray is inversely proportional to the depth of liquid through which it is transmitted; it is concluded that the absorption depends on the number of molecules in the path of the ray. Compare: Beer-Lambert law.

The basic law that is the foundation for all absorption photometry. It predicts the linear relationship between the monochromatic light absorbance (A) of a solution and its concentration (c). The law is given as A = εlc, where A = absorbance, ε = molar absorptivity, l = path distance, and c = concentration. It is also known as the Beer-Lamber or Bougher-Beer law.

Beer-Lambert law - the absorbance of light is directly proportional to the thickness of the ligand through which the light is being transmitted multiplied by the concentration of absorbing chromophore.
Beer law - the intensity of a color or of a light ray is inversely proportional to the depth of liquid through which it is transmitted.
