The description of electromagnetic radiation as waves or vibrations in the medium of the universal lattice makes no mention of photons. One might wonder how this theory corresponds with experimental evidence showing a particulate nature of EM radiation. The answer to this is that the experimental evidence does NOT show that EM radiation has a particulate nature. This is merely an interpretation of the experimental results. What the results of the experiments in question actually show is that under certain circumstances, EM radiation is absorbed or emitted in discrete quantities of a certain magnitude called quanta. This phenomenon could equally as well be attributed as a characteristic of the absorbing and emitting mechanisms, rather than a characteristic of the radiation itself. This is likely the case.
