- TL;DR Summary
- I want to know how can we determine ##\psi(x,0)## in a general situation.
First of all, please understand that I am not good at English so I used the translator.
(EDITED by mentor: small edits + added latex...)
After I studied free particles, I wanted to apply what I learned to other situations.
But as you know, to determine the solution of the free particle, you need to have ##psi(x,0)##. Usually, ##psi(x,0)## is given by the textbook problem (like: ##psi(x) = A e^{-x²}##).
However, in other situations (not in the book), there no information is given about psi(x,0).
So I want to know how can we determine ##psi(x,0)## in a general situation.
1) if ##\psi(x,0)## is determined by experiment, we have to measure ##-\infty## to ##+\infty##? How?
2) What kind of ##\psi(x,0)## can a free particle have? And what makes them different?
