Decide how far apart two cars must be on the ground

Reference no: EM13657047

You are looking down at the earth from inside a jetliner flying at an altitude of 9440 m. The pupil of your eye has a diameter of 1.96 mm. Decide how far apart two cars must be on the ground if you are to have any hope of distinguishing among them in red light (wavelength = 667 nm in vacuum).
