If an electron is in (something very close to) an eigenstate of momentum, then the probability distribution for its position is going to have a very high variance, and this is equally true whether the momentum is very small or very large. | |

I wasn't paying attention to the fact that when the wavelength shrinks, its not just a top wave that shrinks, its gor a frequency as well! So let me resay that. When its moving faster, its got a high probability of being at MORE definite places at the same time, and when its moving slower the probability of being at any of those places for sure further away from each other dies out, but it could be either at point A, or a tiny distance away from point A, with around the same probability! The probability wave becomes less steep (more spread out) but also there are less definite peaks! | |

While if its moving faster... its wavelength shrinks so that it's only at one place? | |
