SmokeyBrown:
The Planck Constant is defined as the "proportionality between the energy carried by a photon and the frequency of its associated EM wave". So, to estimate the Planck Constant, you should take the energies of the electrons and divide those values by their respective wavelengths; you should get approximately the same result from either division.
