What is the Difference Between Beer’s Law and Lambert’s Law?

🆚 Go to Comparative Table 🆚

Beer's Law and Lambert's Law are both related to the absorption of light in a substance, but they describe different relationships. The main differences between the two laws are:

  1. Relationship: Beer's Law states that the amount of light absorbed is directly proportional to the solution concentration, while Lambert's Law states that the absorbance and path length are directly proportional.
  2. Statement: Beer's Law was proposed by August Beer, while Lambert's Law was proposed by Johann Heinrich Lambert.

    Here is a table comparing Beer's Law and Lambert's Law:

    Property Beer's Law Lambert's Law
    Proposed by August Beer Johann Heinrich Lambert
    Mathematical relationship A ∝ C (where A is the absorbance and C is the concentration of the solution) A ∝ l (where A is the absorbance and l is the path length of the light)
    Definition The quantity of light absorbed is directly proportional to the concentration of the solution. The absorbance is directly proportional to the path length of the light.
