For a particular compound in a 1.00\,cm cuvette, the molar absorptivity is 1.50×104M−1cm−1 at 520\,nm and 0.80×104M−1cm−1 at 480\,nm. By what factor would the measured absorbance change if the analyst accidentally records the spectrum at 480\,nm instead of 520\,nm, keeping concentration and path length unchanged?
