Main Question or Discussion Point

At the risk of appearing somewhat obsessed, I'll ask something similar to another thread I'd opened previously:

Has anyone ever come across any experiments suggesting that the E=hw law for the energy of photons may require some correction, say, at a specific wavelength range?

At the risk of sounding silly... I think that at the frequencies at which the relation could possibly be violated (high frequencies), we would probably only be able to measure one or the other, and take the other as definition.

The theoretical limit for the wavelength of a photon is the Planck Length, 1.616x10^-35m. Photons with a shorter wavelength than that either do not exist or do not conform to known laws, including E=hf.

Other than that, there's nothing I know of to suggest E=hf doesn't hold up for the entire spectrum.
