The law in atmospheric applications has a modified equation: T = e − m ( T a + T g + T R S + T N O 2 + T w + T O 3 + T r +..) Where, a is the aerosols. g is the mixed gases. RS is the Raman scattering effect. NO 2 is Nitrogen dioxide. w is the water vapour absorption.
WebBeer’s law, also called Lambert-Beer law or Beer-Lambert law, in spectroscopy, a relation concerning the absorption of radiant energy by an absorbing medium. Formulated by … WebBeer’s Law Equation. A=abc. Where, a= molar absorptivity (is a measure of the amount of light absorbed per unit concentration; this value is a constant for a given solution) b = cell path length (usually 1cm) (Cuvette) c = concentration (M) A = abc. Where ab = constant, then A = constant times c. So when we plot this y=mx+b
