These equations reveal that transmittance and absorbance are inversely rerated. that is the more a particular wavelength of light is absorbed by a substance, the less it is transmitted. moreover , the inverse relationship between A and T is not linear , it is logarithmic. therefore , if 50% of the photons of monochromatic light are transmitted by a sample , and 50% of the photons are absorbed T= 0.5 but A is not 0.5, A is 0.3, due to the inverse logarithmic relationship between T and A . lf 10% of the photons of monochromatic light are transmitted by a sample , and 90% of the photons are absorbed , T=0.1, but A is not 0.9 ,A =1.0 when A is 2.0, 99% of the photons of monochromatic light are absorbed , and when A is 3.0, 99.9% of the photons of monochromatic light are absorbed
