Beer–Lambert Law With Decadic Absorbance

The Beer–Lambert law relates the attenuation of light to the properties of the material through which the light is traveling.

The decadic absorbance equals the product of the concentration of the substance, the path length, and the molar absorptivity.

Formula

QuantityVariable[Subscript["A", "10"], "Unitless"] == QuantityVariable["c", "Molarity"]*QuantityVariable["l", "PathLength"]*QuantityVariable["ε", "MolarAbsorptionCoefficient"]

symbol description physical quantity
A10 decadic absorbance "Unitless"
c concentration "Molarity"
l path length "PathLength"
ε molar absorptivity "MolarAbsorptionCoefficient"
