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.
