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.
Determine the characteristic wavelengths if an electron are accelerated through an electric potential to a kinetic energy of 18kev.
