Two stars that are very close may appear to be one. The ability of a telescope to separate their images is called its resolution. The smaller the resolution, the better a telescope's ability to separate images in the sky. In a refracting telescope, resolution ( see the figure ) can be improved by using a lens with a larger diameter D. The relationship between
in degrees and D in meters is given by
, where
is the wavelength of light in meters. The largest refracting telescope in the world is at the University of Chicago. At a wavelength of
meter, its resolution is
. Approximate the diameter of the lens to the nearest hundredth of a meter.
