What size telescope would be required (i.e, what minimum diameter must its primary mirror have) to resolve the two components of a binary star system whose true separation distance is equal to the mean Sun-Earth distance, located a distance of 15 light-years from Earth? Assume that the telescope is viewing it in visible light; start by stating what wavelength you will use as a typical wavelength for visible light.

A charged-couple device (CCD) detector ismounted at the focus of an f/7 reflecting telescope with a D= 50 cm mirror. The CCD chip contains 1024×1024 pixels, with each square pixel being 10μm on a side. How many separate exposures would be required to cover the entire celestial sphere (4π steradians)?
In the dark, your pupil (the aperture of your eye) expands to a diameter of 7 mm. How many times more light can be gathered by a telescope with a 5.5 m diameter than by a fully dark- adapted eye? Increase in light gathered = I times
Astronauts observing from a space station need a telescope with a resolving power of 0.6 arc second at a wavelength of 530 nm and a magnifying power of 220. Design a telescope to meet their needs. (State the necessary primary diameter of the telescope, in m, and the ratio of the focal lengths below.) What will its light-gathering power be, compared with a dark-adapted human eye? (Assume that the pupil of your eye can open to a diameter of about 0.8 cm in dark conditions.)
A powerful telescope can observe an object down to about the 30th magnitude in the B-band. To what distance can this kind of telescope observe a star such as the Sun? What kind of energy flux is observed at this telescope in terms of the solar constant? (Show your work for all calculations)

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
Instead of a dot, sometimes the telescope image of a star looks like concentric rings. This is due to: a)diffraction. b)reflection. c)refraction. d)scatter.
In order to observe emissions from celestial bodies Very Long Baseline Arrays (VLBA) have been developed. Explain why VLBA use multiple telescopes separated by long distances in terms of the wave nature of light. Include in your answer specific physics terminology, associated relevant equations, and a labelled diagram.
