probability wave Scientific  

1. A quantum state of a particle or system, as characterized by a wave propagating through space, in which the square of the magnitude of the wave at any given point corresponds to the probability of finding the particle at that point. Mathematically, a probability wave is described by the wave function, which is a solution to the wave equation describing the system.
