Question

beer lambert law definition

Answer 1

The Beer-Lambert law (or Beer's law) is the linear relationship between absorbance and concentration of an absorbing species. The general Beer-Lambert lawis usually written as: A = a( ) * b * c.

Answer 2

Beer’s law

 A law stating that the concentration of an analyte is directly proportional to the amount of light absorbed, or inversely proportional to the logarithm of the transmitted light.

Beer’s law
A = abc = log(100/%T) 2 - log %T

where: 
A = absorbance
a = absorptivity
b = light path of the solution in cm
c = concentration of the substance of interest
%T = per cent transmittance—the ratio of transmitted light to incident light
