WebBeer's Law: The absorbance is directly proportional to the molar concentration of solution. A ∝ C Lambert's Law: The absorbance is directly proportinal to the optical path length. A ∝ x on combining these two laws we get-A ∝ C x A = εCx Absorbance: Absorbance is the maximum capacity of a substance to absorb light of any specified wavelength. . … WebJun 28, 2024 · Lambert’s law suggests that a sample’s absorbance is proportional to the path length of light passing through it. This law is frequently used in combination with Beer’s law, resulting in the Beer-Lambert law. This is because, in addition to these separate rules, the Beer-Lambert law is very useful in spectroscopic analysis.
