Question

Every motor vehicle must have a rearview mirror that reflects to the driver a clear view of the road for a distance of at least ________?

Answer 1

The maximum distance at which the eye can resolve the two headlights of a car depends on the pupil diameter and the distance between the headlights. We can use the concept of angular resolution to determine this distance.

Step-by-step explanation:

The maximum distance at which the eye can resolve the two headlights of a car depends on the pupil diameter and the distance between the headlights. We can use the concept of angular resolution to determine this distance. Angular resolution is defined as the smallest angle that can be resolved by the eye. It is given by the formula:

Angular resolution = 1.22 * (wavelength of light) / (pupil diameter)

For headlights that are 1.3 meters apart, we can assume that the distance between the two headlights is equal to the minimum resolvable distance. Using the formula, we can calculate the maximum distance at which the eye can resolve the two headlights.
