Single slit single electron

  1. Oct 30, 2007 #1
    1. The problem statement, all variables and given/known data

    A single electron with de Broglie wavelength λ passes through a slit of width d=2λ.The electron can strike a fluoroscent screen.What will be observed on the screen?

    (a)a diffraction pattern
    (b)a single flash as if the electron had moved in a straight line through the slit.
    (c)a single flash that could occur anywhere on the screen.
    (d)a single flash that would most likely occur where a corresponding diffraction pattern would have the highest intensity.

    2. Relevant equations

    a sinθ=λ

    3. The attempt at a solution

    (a)clearly wrong
    (b)wrong as electron must have interacted with the slit
    (c)It seems incorrect as it means that the flash can occur even at a remote end of the screen also where the electron may not possily reach...
    (d)looks correct to me...

    Please let me know if I am correct
