Absorptivity for gases in Beer-Lambert law (given in and out intensity of the radiation)
Formula
A
absorptivity for gases
I
the intensity of the radiation coming out of the sample
I0
the intensity of the radiation coming out of the sample
Formula description
Beer-Lambert law states that there is a logarithmic dependence between the transmissivity of light through a substance and the product of the absorption coefficient of the substance and the distance the light travels through the material.
