Mizar is a multiple star system in the handle of the Big Dipper that appears as a single dot when
observed by eye. With a typical backyard telescope, you can see Mizar A and Mizar B as two
separate dots that are 14.4 arcseconds apart. What is the minimum diameter of an optical telescope that can always distinguish these as two separate stars? Visible light has a wavelength of approximately 5 x 10–7 meters.
