Dish resolution and GHz

  1. Apr 24, 2007 #1
    1. The problem statement, all variables and given/known dataA dish operates at a frequency of 4 GHz and has a diameter of 3 m. What is its resolution?

    2. Relevant equations
    my take home quiz referres me to a page number in my book for the equation, but I have an older book so I cant find it. i think it is the equation for the Limiting angle of resolution of a circular aperture, but I am not sure. something like:
    x = 1.22(y GHz/ D) is this what I am looking for?

    3. The attempt at a solution
    If I try it with this equation I get: 1.63 degrees. any help is appreciated. thanks.

    As long as "y GHz" means the wavelength.
