Angular resolution
Technological advances are now making it possible to link visiblelight telescopes so that they can achieve the same angular resolution as a single telescope over 300 meters in size.
What is the angular resolution (diffraction limit) of such a system of telescopes for observations at a wavelength of 500 nanometers?
Hey guys, so I've been stuck on this for a while and I just can't figure it out, I have one attempt left..
I've been using the formula sin theta = 1.220 * wavelength/ diameter
So I use sin theta = 1.220 * (5.0*10^7/300) = 2.03 *10 ^9
sin (2.03*10^9) = 3.54...*10^11 arc seconds?
Please let me know if this is right or what I'm doing wrong.

Link for anyone who wants to know how to do it.
