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 1.5 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.

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
