The squared absolute value of its wave function tells where we would classically think of the particle as a spending most its time. Ψ 2 is the probability distribution function for the position of the particle. Q41.2 The motion of the quantum particle does not consist of moving through successive points. The particle has no definite position. It can sometimes be found on one side of a node and sometimes on the other side, but never at the node itself. There is no contradiction here, for the quantum particle is moving as
