Question

In the question below, I believe that the correct answer is Wavelength = 600; Percent transmittance (%T) =3.91, because the amount of transmittance is the lowest meaning the amount of light absorbed is the greatest. I don't believe wavelength matters here but I want to be sure.

A student determined the following percent transmittances for a 0.5 M chromium ion solution using a Spectronic 20 spectrophotometer. Which wavelength has the greatest absorbance? _____________

Wavelength = 625; Percent transmittance (%T) = 6.92

Wavelength = 600; Percent transmittance (%T) =3.91

Wavelength = 575; Percent transmittance (%T) =4.05

Wavelength = 550; Percent transmittance (%T) =7.16

Explanation / Answer

Wavelength = 600; Percent transmittance (%T) =3.91
