Final answer:
The question is about the resolving power of the human eye for car headlights at a distance, but the provided content does not contain adequate information to calculate the exact distance. It highlights general facts about low beam headlights and their design for safe night driving.
Step-by-step explanation:
The question pertains to the ability of human vision to resolve two separate points of light, specifically the headlights of a car, which are typically 1.3 meters apart. For a pair of lights to be resolvable, the angle subtended by the lights at the eye must be equal to or greater than the resolving power of the human eye. The resolving power of the eye is dependent on the diameter of the pupil, which is taken to be 0.40 cm in this scenario. To solve this problem, one would typically use the Rayleigh criterion in the context of wave optics. However, the provided content does not offer sufficient information to directly calculate the maximum distance. Nevertheless, we can discuss the fact that low beam headlights are designed to provide adequate visibility without blinding oncoming traffic and that the content loaded in the headlights help form a directional beam to illuminate the road ahead.
