- 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.None9

If 2 = 6.6 x 10-7 m, what is the smallest aperture (diameter) telescope that may be used to resolve the two stars? Write your answer in cm.A certain telescope has a 10' × 10' field of view that is re- corded using a CCD chip having 2048 x 2048 pixels. What angle on the sky corresponds to 1 pixel?

(Hint: Look up the conversion of light years to meters.)
- Question:-A binary star consists of two stars orbiting each other. Suppose a binary pair is known to be 580.0 light years away from Earth. How far apart are the two stars from each other, in light years, if they can just be resolved by a telescope with an aperture of 50 cm (0.50 m), using visible light (l = 550 nm)? (1 nm = 1 x 10-9 m)Spy planes fly at extremely high altitudes (25 km) to avoidinterception.
