QUESTION 27 Why is it generally preferable to use absorbance as a measure of sample absorption rather than % transmittance? O a. absorbance is proportional to the concentration of the analyte, whereas %T is not O b.%T is dependent on the power of the incident radiation O c. %T cannot be measured as accurately as absorbance O d. most commercially available silicon detectors are not as sensitive to %T
