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.

Fascinating! I'll need to think on this data.

Thank you.

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 .

Because light photons are emitted in all directions.

Any experiment that confirms you statement?

The best known is probably the double slit experiment. I'm sure you will have come across this.

Exactly

At all times .

Which produces a wave .
