Concept explainers

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

Question

Let's pretend your little cousin walked in on you as you were performing your
experiment. They took your dyed liquid and made their own sample by diluting it with
water just as you did. However you did not see how much water they added.
Assume the graph below represents your measured results. Now lets say you take one
more image using your little cousin's sample of unknown concentration, and you
calculate the absorption value to be 0.34. What is the approximate concentration of the
solution that your little cousin mixed?
