1. Hi all, I am doing a practice exam attempt and I am stuck on this question: What is the physical interpretation of |ψ(r,t)| and |ψ(r,t)|^2? Can the wavefunction |ψ(r,t)| be measured directly? My attempt was: The Schrodinger equation describes the relationship between the energy and momentum of a particle. Wavefunction squared explains the probability of finding a particle in a given region. And the wave function can't be measured directly. Any help would be appreciated, thanks.
