Single slit interference

  1. Mar 28, 2006 #1
    i really dont know where to start with this problem

    Consider the setup of a single slit experiment

    The first minimum for 440 nm light is at y1.
    The first minimum for 529 nm light is at y2.

    what is the ratio of y2/y1?

    i know that the distance between two max is
    (wavelength*dis between the slit and the screen)/(dis slit seperation)

    Careful. For a single slit experiment, the position of the first minimum is given by:
    [tex]y = \lambda \frac{D}{a}[/tex]
    where D = distance to screen; a = width of the slit
