np If two solutions of the same colored compound are made in the same solvent, one of which is, say, twice the concentration of the other, the absorption due to a given thickness of the first solution should be equal to that of twice the thickness of the second. Mathematically this may be expressed as l1c1 = l2c2 when the intensity of light passing through the two solutions is a constant and if the intensity and wavelength of light intensity and wavelength of light incident upon each solution are the same. See  Absorption Coefficient.
