Problem for the extra credit: a telescope consists of a single pos- itive lens of diameter 1 m and focal length 20 m and a ccd camera with 2048 x 2048 square pixels with 9 um big pixels, placed in the focus of the lens. tele- scope is observing a binary star with two components, separated by 3 x 108 km, 5 light-years away. what is the angular resolution of this telescope? can the telescope see these two stars separated? (i. e. can it 'resolve them)? if yes, what is the distance between the stars on the ccd image (in pixels)? how big are the images of the stars on the ccd (in pixels)? what is the 'field of view of the camera? (the angular span it can cover, so to speak). assume the telescope observes at the wavelength 500 nm.
