When I read about the uncertainty principle, I keep reading about these experiments where they fire electrons through a single or double slit and observe the diffraction but I can't these experiments relate to Heisenbergs uncertainty principle. So when they fire the electrons, they know their momenta, then when they reach the slit, they diffract and their momenta changes and eventually, when they hit the screens, they know their positions. I'm real confused, how do these experiments show that when you know the momentum of a particle, you can't know its position and vice versa?
