The two headlights of an approaching automobile are 1.5 m apart. Assume that the pupil diameter of theobserver is 4.4 mm, and use a wavelength of 550 nm for the light. Also assume that diffractioneffects alone limit the resolution.
(a) At what angular separation will the eye resolve thetwo headlights?
rad
(b) At what maximum distance will this occur?
km
