Why does Beer–Lambert law matter?
This principle is one of the building blocks physicists use to explain the world. Without it, a whole class of phenomena would have no mathematical description. Engineers, chemists, and astronomers all rely on it.
A is the absorbance
ε is a constant
c is the concentration of the absorbing substance
l is the path length
Forms of the law date back to the mid-eighteenth century, but it only took its modern form during the early twentieth.

Background: Beer–Lambert law
The Beer–Lambert law (also known as Beer’s law) is used to determine the concentration of substances in a solution. It describes how the amount of light that a solution absorbs is directly proportional to the solution's concentration. This relationship is commonly expressed as A = εcl, where
A is the absorbance
ε is a constant
c is the concentration of the absorbing substance
l is the path length
Forms of the law date back to the mid-eighteenth century, but it only took its modern form during the early twentieth.
