Since energy is What gives you that idea? The wavelength is just the distance from peak to peak (or trough to trough) of the electric (or magnetic) portion of the wave. I've never heard that photons were exactly "one wavelength long". More likely, all photons are something like a meter long (or a millimeter or a kilometer), and photons with a shorter wavelength just have more "wiggles" crammed into that one standard photon length. (I HAVE wondered how big "across" photons were, i.e. how close together do two light beams have to be before they'll interfere with each other?)
