Hi,
Ok so this formula E = h*c/? gives the energy of a "photon". To simplify that formula, it could be thought of as E = amplitude / wavelength, with the h constant scaling the amplitude correctly, and the c constant scaling the wavelength constant correctly.
One interesting thing from this formula is it apparently shows that all "photons" aka electromagnetic waves resulting from electron orbital emissions, have the same amplitude! So this must mean that all electron orbital emissions and absorptions (which are frequency keyed) must all emit or absorb electromagnetic waves with the same fixed amplitude, regardless what the orbital number is. I find that to be quite amazing and hard to understand why that would occur.
cheers, Jamie
