When light emitted by an atom that propagates throughout spacetime, does wave/particle duality describe what light is or what light is doing?
If the wave aspect of light describes how light is tracked from one point of spacetime to another point in spacetime as it propagates throughout the universe then that doesn't tell us what light is but merely describes its motion.
And if the particle aspect of light shows us where an interaction took place i.e. the wave collapses due to some interaction (reflection, refraction or absorption) which produces a photon(s) that we can detect, then that also doesn't tells us what light is because interactions describe how things behaved not what things are.
Light is described by its wave like nature and particle like nature and that it is mass less and that it has momentum and ect but that does not answer question, what is light?
