Transmittance for liquids by Beer-Lambert law (given molar absorption coefficient,concentration)

Formula

Transmittance for liquids by Beer-Lambert law (given molar absorption coefficient,concentration) formula
T
transmittance of light through the measured substance for liquids
l
distance the light travels through the material (i.e. the path length)
epsilon
molar absorption coefficient of the absorber
c
concentration of absorbing species in the material

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.
