How true can be the following statement ? Quantum Mechanics is made up of two stages: 1- a probabilities stage and 2- a resolution stage. Wave-particle duality is in the first stage. The resolution will finally tell us if light is a wave, a particle or something else.
No. The wavelike stage is the probability stage. The resolution ("wave function collapse", as a result of an interaction) leads to a particle-like outcome. The wave function is a bit like a wave of the square root of a probability distribution: if you multiply it by its complex conjugate to get the square modulus, you have the probability density. However measurements of individual QM entities produce a particle-like result, subject to precision limitations governed by the uncertainty principle.
Light is both . The best way I know to understand this is in water . The particle in water is the H2O molecule . The wave is the density of H2O . So an ocean wave is both particle and wave .
But, in the water the molecule doesn't move with the wave, in the light the particle moves with the wave.
I see your point . But if that were true , then why is there a distribution of light three dimensionally . As in light filling a room .
