Assume you are standing on a straight high way and watching a car moving away from you. The air is perfectly clear, and after awhile you see only one taillight. Suppose the diameter of your pupils 4.0mm and the index of refraction of your eye is 1.38, and the width of the car is 120cm. (Taillights are red, so utilize a wavelength of 650nm).
1. What is the wavelength of the taillights inside your eye?
2. What is the angular resolution of your eye at the wavelength of the taillights?
3. Estimate the distance among you and the car.
