Planck s constant is a fundamental physical constant used to describe the energy of a photon. Spectrophotometry and basic circuit analysis techniques are employed to obtain empirical data with respect to the energy of the emitted photons of light and thus used to calculated planck s constant. If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been.
