Question

The representation of Beer Lambert’s law is given as A = abc. If ‘b’ represents distance, ‘c’ represents concentration and ‘A’ represents absorption, what does ‘a’ represent?

(a) Intensity

(b) Transmittance

(c) Absorptivity

(d) Admittance

The question was posed to me during an interview.

I need to ask this question from Introduction to UV Visible Spectrometers in division Colorimetry and Spectrometry of Analytical Instrumentation

Answer 1

Right answer is (c) Absorptivity

To explain I would say: ‘a’ represents the absorption constant. It is also known as absorptivity.
