WebBy definition, internal transmittance is related to optical depthand to absorbanceas T=e−τ=10−A,{\displaystyle T=e^{-\tau }=10^{-A},} where τis the optical depth; Ais the absorbance. The Beer–Lambert lawstates that, for Nattenuating species in … WebApr 8, 2024 · Optical density (O.D.) = log₁₀ Io / It. The optical density of any medium is defined as the logarithmic ratio of the intensity of incident light (Io) to the intensity of the transmitted light (It) passing through that medium. The O.D value for absorbance can be computed by the formula given by, O.D. Value. Absorbance (A) = log₁₀ (100 ...
