Hi, I'm fairly new to quantum physics so go easy on me! I've just come across the uncertainty principle and have some confusion over wave packets. If we superimpose multiple waves then as I understand it we get a wave packet with a finite length which lowers the uncertainty in position. If your talking about electrons say, then where do these multiple wave come from? If an electron is a wave then how can you superimpose multiple waves wouldn't that be superimposing many electrons which doesn't make sense to me? Thank you for any help offered.
