Thread: Angular resolution

Technological advances are now making it possible to link visible-light 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.
