The two headlights of an approaching automobile are 1.3 m apart. At what (a) angular separation and (b) maximum distance will the eye resolve them? Suppose that the pupil diameter is 5.0 mm, and utilize a wavelength of 514 nm for the light. Also suppose that diffraction effects alone limit the resolution so that Rayleigh's criterion can be applied, in meters.
