question 23

Multiple Choice

The 200-in reflecting telescope at Mt.Palomar has an objective mirror with a focal length of 16.8 m.The effective aperture is the diameter of the 200-in mirror (200 in = 5.08 m) .For light in the blue region (450 nm) ,what is the smallest angle between two stars that this telescope can ideally resolve? (In practice,the limit of resolution is due to atmospheric turbulence.)
