Headlights as two separate lights

Reference no: EM13667562

The headlights on a certain car are gauged to be 1 m apart. The diameter of the pupil in a human eye is 2.5 mm. What is the furthest distance at which a human eye could obviously see the headlights as two separate lights? Use a wavelength of 644 nm/wave.
