WebFeb 12, 2024 · Transmittance is related to absorption by the expression: \(Absorbance (A) = - log(T) = - log(\dfrac{I_t}{I_o})\) Where absorbance stands for the amount of photons … WebWhat is the absorbance in absorbance units of a solution which has 1% transmittance? Absorbance is measured in absorbance units (Au), which relate to transmittance as seen in figure 1. For example, ~1.0Au is equal to 10% transmittance, ~2.0Au is equal to 1% transmittance, and so on in a logarithmic trend.
