Use the Rayleigh criterion to estimate how far away (in km) you could be from the red taillights of a car and still distinguish them as separate lights. Assume that the lights are separated by 1.1 m, that the pupil is about 4.0 mm in diameter, that the wavelength is 650 nm, and that the intensity of the lights is sufficiently large that you can still see the car.

b would be the answer

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

i had this question and the answer was 3.15 miles.
