>>11141549If you close your eyes and toss a ball you have no idea where it really is without observing it. So if you were to build up a function representing its probability to be in every possible location, that's effectively wave function.
When it comes to physics really tiny things happen to act as both particles and waves depending on if they're observed or not, the wave function of something represents its probability to beat a certain location.
Things like quantum tunneling happens if the wave function has a portion outside of some boundary, when you observe it theres a chance for it to exist beyond said boundary and so it jumps there.
Or something like that
