Homework Statement
At first I needed to calculate the angular resolution of a telescope (diameter 1m, for visible light) so I used θ=1.22λ/D and got 4.88x10^-7 rad. Now I am asked: "If we wished to use this telescope to image the moon, what is the closest distance two objects can be to be distinguished by such a telescope?"
I don't understand what the relationship between angular resolution and distance is.
