Lambert Beer Law is a formula used to calculate the absorption of light by a substance.

• It states that the absorbance of a substance is directly proportional to its concentration and the path length of the light through the substance.

• It is commonly used in chemistry and spectroscopy to determine the concentration of a substance in a solution.

• The law can be expressed as A = εcl, where A is the absorbance, ε is the molar ...read more
