1) While driving at night, your pupils dilate to 3.1mm diameter. An oncoming car has two headlights spaced 1.5m apart. If your vision were diffraction limited, what would be the greatest distance at which you could see the two headlights distinctly? Assume the headlights emit light at wavelength 550 nm.

2) A tanker ship spills oil (n=1.40) into the sea. Looking at this disaster from a helicopter overhead, what predominant wavelength of visible light do you see if the oil is 390nm thick?
