Estimate the farthest away a car can be at night so that your eyes can resolve the two headlights. Indicate any assumptions you made.
The headlights on a particular car are separated by a distance of 1.4 meters and emit predominantly yellow light of wavelength 550 nm. One night, the car is heading towards you from a very long distance away on a long straight road. Under the low light conditions, the pupils of your eyes have diameters of about 6.8 mm. At what distance would you only just be able to resolve the two headlights?
