Document Summary
Where io intensity of the incident radiation. Length of the absorbing medium (thickness) k a constant called linear absorption coefficient. Hence the law may be stated the amount of light log l absorbed is proportional to the thickness of the absorbing medium. C concentration ; k1 absorptivity constant. Io intensity of the incident radiation & it intensity of the transmitted radiation. The product kc is constant c concentration of the solution log i. e. , 0 kcl k the molar adsorption coefficient i. e. , log. Cl (this is a mathematical form of beer lambert"s law) k. , molar extinction coefficient or molar absorptivity or molar absorbance it is a constant for a particular solution. log. When a is plotted against c, a straight line is obtained. A = 0, for a perfect transparent medium and a is infinity for perfect opaque medium. C : to determine the concentration of a solution :-
