Is The Complex Probability Anplitude ψ Just A Neat Trick? |
|
Answer» No, it’s not. It or something like it is necessary. As we said, to represent a free particle of fixed ENERGY (or k), you need a |ψ|2 that is UNIFORM, that is the PROBABILITY of finding the particle is the same everywhere. But at the same time that function ψ MUST be able to produce wave-like interference effects. The only way anyone KNOWS how to do this is to use the complex probability amplitude function.
