Tennis ball diffraction angles

  1. Dec 6, 2007 #1
    1. The problem statement, all variables and given/known data
    Quantum effects are negligible in "macroscopic" world.
    Show than on example.
    A tennis ball with speed 0.5 m/s is thrown thru a window.
    Dimensions of a window are 1*1.5 m.
    Calculate vertical and horizontal diffraction angles.

    2. Relevant equations

    3. The attempt at a solution
    For horizontal diffraction angle.

    I assumed that n=1.



    from this I would conclude thath, alpha is negligible small, that is
    quantum effect are negligible.
    I would do the same thing for vertical angle.
    I' not shure if I'm right ?
