Would collapsing wave function by measuring/observing and then quickly turning off measurement device cause to uncollapse wave function? so it goes like this : wave--->particle---> wave(hits the wall)
Collapse is a misleading concept for a wavefunction leading to thinking that a wave function is a balloon that can collapse , then why not be filled up again?
Collapse of a wavefunction describing a particle means that an interaction happened. At the interaction time a new wavefunction describes the setup, dependent on the boundary conditions of the interaction. To get the original wavefunction back one would have to have the original boundary conditions and potential problem.
Would collapsing wave function by measuring/observing
Interaction= changed wavefunction.
and then quickly turning off measurement device cause to uncollapse wave function?
the measurement is at an instant anyway, and the particle travels with that wavefunction.
so it goes like this : wave--->particle---> wave(hits the wall)
No. The wave part describes the probability distribution of the particle. When it interacts one instance of that probability distribution is sampled. Probabilities do not hit a wall. Probabilities are sampled by interaction=hitting-the-wall. Interaction is always a particle, which interaction happens with a given probability.
