What is the Lambert Beer's law?

Question

Accepted Answer

Lambert Beer's law relates the concentration of a solution to the amount of light absorbed by the solution.

The law states that the absorbance of a solution is directly proportional to its concentration and the path length of the light through the solution.
It is commonly used in spectrophotometry to determine the concentration of a substance in a solution.
The law assumes that the solution is homogeneous, the absorbing species is in a single form, and the incident light is monochromatic.
The law can be expressed as A = εcl, where A is the absorbance, ε is the molar absorptivity, c is the concentration, and l is the path length.
The law is named after Johann Heinrich Lambert and August Beer, who independently discovered it in the 18th and 19th centuries, respectively.

Accepted Answer

Intensity of monochromatic light absorbed by the substance. Dissolve in fully transmitting solvents is directly proportional to the substance, concentration and is the path length of the light through the solution.
