Absorption Spectroscopy Experiment

I need help describing an experiment where one could measure the value of the extinction coefficient of a solution with a concentration (c mol/L) of chlorophyll in water for a given wavelength. **This does not need to be a lengthy answer, nor does it need to describe all the materials needed---I really just need something conceptual. Inclusion of any used equations or measured values however would be useful.

Question: I need help describing an experiment where one could measure the value of the extinction coefficient of a solution with a concentration (c mol/L) of chlorophyll in water for a given wavelength.
Solution:
Spectrophotometers determine the absorbance (optical density) of a solution by measuring the amount of light that passes through a solution. Multiple wavelength light is first passed through a prism which focuses a single wavelength of light on a slit. This monochromatic light passes through the sample ...
