Final answer:
High beam headlights typically allow you to see around 350 feet ahead, which is connected to the limit of the eye's acuity and the diffraction by the pupil. Option b) is correct.
Step-by-step explanation:
The distance your high beam headlights will allow you to see ahead varies depending on the make and model of the vehicle, but a common standard is that high beams should enable you to see about 350 feet ahead. This is important for safety at night or in poor visibility conditions, allowing drivers enough time to react to obstacles or changes in the road.
Understanding the limit to the eye's acuity, which is related to diffraction by the pupil, is essential when considering visibility distances. For example, the greatest possible distance a car can be from you if you can resolve its two headlights, given they are 1.30 meters apart, can be determined using diffraction and the properties of the human eye's pupil.
