Question: In optical absorption spectroscopy, we use Beer Lamberts law, which relates the absorbance (A) oroptical density of a specimen to the path length and concentration

In optical absorption spectroscopy, we use Beer Lambert’s law, which relates the absorbance (A) oroptical density of a specimen to the path length and concentration of the absorbing species:A = ϵclThe absorbance (also called optical density) is defined as A = log!" (#!# ), where I" and I are theintensities of light incident on the sample and after the sample respectively.a. If a sample has an optical density of 0.3. What fraction of the incident light is absorbed by the sample?
