Please bear with me as I have been reading about quantum physics and, not being a physicist, I have some questions regarding the nature of wave-particle duality. First of all, according to the special theory of relativity a particle with a rest mass would need infinite energy to accelerate to the speed of light. If this is the case, how is it possible for electromagnetic radiation to consist of particles? Second, is it possible that instead of EMR being thought of as a wave-particle duality to think of it as oscillating between being a wave and a particle? In other words, can EMR change from a wave state to a particle state at the node of a wave, before changing back to a wave state? This to me would explain why the quantum nature of light becomes more apparent at higher frequencies than at lower frequencies since there would be more nodes per unit of time with higher frequency photons than with lower-frequency photons. Thoughts and/or explanations would be welcome. Just keep it simple please.
