You just finished building your own reflecting telescope to observe your favorite star. If the telescope diameter is 5 meters, approximately what angular resolution (in arcseconds) ill the telescope have when observing blue-green light with a wavelength of 500 nanometers? HINT: you should convert the wavelength to meters first; HINT2: 1 meter = 10⁹ nanometers; HINT3: a calculator might actually be helpful here)
