a particularly energetic photon

Several people have posted asking about "particularly energetic photons."  The more energy a photon has, the more its wavelength shifts toward the blue.  So there is no such thing as particularly energetic 633 nm (red) photon for instance.  All photons at a given wavelength have the same energy.
