   Yea.  Beyond that there is an implied 'frequency' or 'wavelength'   
   in the theoretical energy or momentum of the photon.   
      
   I think that it is all based upon a esoteric mystical phenomenon   
   coming from not defining terms.  Point and curve have reasonably   
   good meanings in mathematics, but 'particle' and 'wave' are just   
   different enough for people to sort of claim they have no meaning   
   at all, but then say 'stupid' and back track and bait and switch   
   'particle' and 'wave' with 'point' and 'curve'.   
      
   Then of course there is the Fourier transform.  Any curve can   
   be represented by an set of sine wave equations, just as the   
   Laplace transform for exponential equations.   
      
   Probably it is best to just keep it simple.  A photon is an   
   increment of energy or momentum transfer from the Schrodinger   
   equation curve.  Beyond that do not get into strange mysticism.
