If my understanding of the theory is correct, the fact that very low light is detected on a CCD at points demonstrates light's behavior as a particle. For, if light acted as a wave in this instance, we would see not points but vectors (lines) registered on the CCD, that is, representing entire wave-fronts. My question is this. Was it expected, if the light had been detected as waves, that the wave-fronts would've been detected along their magnetic vector, their electric vector, or both (forming a cross)? The question also pertains to light waves in general. Are they thought to deliver their energy in a particular way in relation to their magnetic and electric fields?
