The resolution of a telescope is ultimately limited by the diameter of its objective lens or mirror. A typical amateur astronomer's telescope may have a 5.94 in diameter mirror. What is the minimum angular separation (in arc seconds) of two stars that can be resolved with a 5.94 in scope? (Take $\lambda$ to be at the center of the visible spectrum, 543 nm.) Give answer in arc second. Do not enter unit.
