The diameter of the Arecibo radio telescope is 307 m. It can image radio source that emit electromagnetic waves with wavelength between 3 cm and 1 m. The Virgo Cluster is a cluster of galaxies whose center is ~53.8 Mly away from us. Assume the telescope is imaging at a wavelength of 63.3 cm and can just resolve two point sources of radio waves in the Virgo cluster. How close together could these point sources be, i.e. what is the minim distance between them in ly? Enter an integer.
