Beer Lambert Law Calculator

This is a calculator to find a missing Beer Lambert Law equation value. The formula sets absorbance equal to extinction coefficient (molar absorptivity) in M-1 cm-1 multiplied by path length and concentration. This calculator can be used to find the amount light absorbed by the medium it is passing through.
