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:
- 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.
- Statement: Beer's Law was proposed by August Beer, while Lambert's Law was proposed by Johann Heinrich Lambert.

Comparative Table: Beer’s Law vs Lambert’s Law
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. |
