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?

You are the leader of the international Event Horizon Telescope, a collaboration of radio astronomers who want to take a picture of the black hole at the center of the Milky Way (Sag. A*). That black hole has a mass of about 4.1 million solar masses and is about 8 kpc away. If you are observing with a radio wavelength of about 1 mm, what effective diameter of your radio interferometric array is needed in order to just resolve the diameter of the Sag. A* black hole event horizon. (Assume the black hole is non-spinning, so its diameter is twice the event horizon radius.) Express your answer as a multiple of the Earth's radius. [Hint: you will need to recall and combine three formulas introduced throughout this course, including one about how big a black hole is, one about the criterion for resolving objects, and another that relates distance, sizes, and angles.] There really is an Event Horizon Telescope, and they are responsible for the first image of a black hole in the galaxy M87…
Quasars are recent additions to our body of knowledge about the physical universe. Quasars (quasi-stellar objects) are astronomical objects that are star like in appearance and emit non- thermal radiation, usually more ultraviolet and infrared radiation than stars. a Quasars were first discovered in the early 1960s when telescopes picked up mysterious radio- wave emission sources that, at the time, could not be explained. Since then, thousands of radio- emitting and radio-quiet quasars have been located. One interesting feature of quasars is that their energy output can change by great amounts in a short period of time. To date, scientists have not been able to account for these energy changes. 35.

For a human eye with a pupil diameter (aperture diameter D) of 0.005 meters, and a focal length of 0.022 meters, there will be a resolution limit due to diffraction at 0.6 microns (10^-6 meters) wavelength. If we space light-sensitive cells on the retina at this spacing, how many retina cells per meter (of retina) are there? cells/meter. Now suppose there are giants which are exactly twice the size of humans in each dimension. So giant eyes have pupils of 0.01 meters, and a focal length of 0.044 meters. How many retina cells per meter should the giants have? cells/meter
