Transmittance,T,is defined as the intensity of light transmitted through a sample divided by the intensity of light incident on the sample.The absorbance,A,is defined as

Question

Quizplus · Accepted Answer

The absorbance is defined as A = -log T, so this is the best choice. Choice B is incorrect because taking the log of a negative number is undefined. Choices C through E are all incorrect because they involve variables and operations that are not defined or relevant to the definitions of transmittance and absorbance.
