Chapter 37, Problem 37AP
The Very Large Array (VLA) is a set of 27 radio telescope dishes in Catron and Socorro counties, New Mexico (Fig. P37.37). The antennas can be moved apart on railroad tracks, and their combined signals give the resolving power of a synthetic aperture 36.0 km in diameter. (a) If the detectors are tuned to a frequency of 1.40 GHz, what is the angular resolution of the VLA? (b) Clouds of interstellar hydrogen

The Square Kilometers Array (SKA) is a set of thousands of radio dipole antennae and telescope dishes that is planned to be build, starting in 2016. It is to spread out over a distance of more then 3000 km. The combined signals will have a resolving power equivalent to that of an aperture of approximately 1000 km (a) If the detector are turned to a frequency of , what is the angular resolution of SKA? (b) Clouds of interstellar hydrogen radiate at a frequency used in part (a). What must be the separation distance of two clouds at the center of galaxy, 26000 light years away, if they are to be resolved?
The FAST radio telescope in China is currently the largest in the world, with a diameter of 500 meters. It is able to detect radio waves across a wide spectrum, but let's
assume it is "tuned" to a frequency of 1 Giga-Hertz (10°cycles per second). What is the angular resolution limit of the FAST telescope at this frequency?
A telescope can be used to enlarge the diameter of a laser beam and limit diffraction spreading. The laser beam is sent through the telescope in opposite the normal direction and can then be projected onto a satellite or the Moon. If this is done with the Otto Struve telescope, producing a 2.10 m diameter beam of 613 nm light, what is the minimum angular spread of the beam?
minimum angular spread:

Neglecting atmospheric effects, what is the size of the spot this beam would make on the Moon, assuming a lunar distance of 3.84×108 m?
