The headlights of a car are 1.3 m apart. What is the maximum distance at which the eye can resolve these two headlights? Take the pupil diameter to be 0.40 cm.

the angular resolution off eyes given by better that is equal to 1.22 times the prevalent off a light for the visible light that is a 5 15 enemy deerskin warding into meters that exit into the powers minus nine, divided by the diameter off the oh human eye lens. Ah, that is a 0.4 old times 10 to the power a minus four meat minus two meters. Deriding this, we get the resolution. If I which is 1.67 75 times 10 to the power minus four Indians minus four radiance, then we can find the distance. Do the headlights off the car by writing your relation. That is our times a tater r is the distance to the card is equal to the X X is the distance between the two lights headlights Then we console for are here Why you riding picks? Well, you better so x given we have here is 1.3 meters derided by the angle we just got which is the 1.6775 time stand to the ball at minus four. Etienne, writing these two numbers gives us the distance in the car is, um, 7.74 kilometer. So for this distance, the person or a human can resolve the two headlights off the car.
