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?

Two starships, the Enterprise and the Constitution, are approaching each other head-on from a great distance. The separation between them is decreasing at a rate of 812.5 km/skm/s. The Enterprise sends a laser signal toward the Constitution.
If the Constitution observes a wavelength λ=675.3nm, what wavelength was emitted by the Enterprise?
