Momentum & position

  1. Apr 9, 2008 #1
    Is it possible to know both the y-coordinate and the momentum in the x-direction at the same time?

    (I know that you can not know the x-coordinate and the momentum in the x-direction, but i'm not sure about y-coordinate)

    Yes, because those operators commute.
