The two headlights of an approaching automobile are 1.4 m apart. At what (a) angular separation and (b) maximum distance will the eye resolve them? Assume that the pupil diameter is 5.0 mm, and use a wavelength of 524 nm for the light. Also assume that diffraction effects alone limit the resolution so that Rayleigh's criterion can be applied, in meters.
