Two stars are 5.3 × 1011 m apart
and are equally distant from the earth. A telescope has an
objective lens with a diameter of 1.26 m and just
detects these stars as separate objects. Assume that light of
wavelength 470 nm is being observed. Also, assume
that diffraction effects, rather than atmospheric turbulence, limit
the resolving power of the telescope. Find the maximum distance
that these stars could be from the earth.
