MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Working on your car you spill oil (index of refraction = 1.55) on the ground into a puddle of water (n = 1.33). You notice a rainbow pattern appear across the oil slick. Recalling the lessons you learned in physics class, you realize you can calculate where constructive and destructive interference occurs based on the thickness of the oil slick. (Assume that the average wavelength is 592 nm.) n air n *oil d. n water (a) What are the first three thicknesses necessary for constructive interference? nm nm nm (b) What are the first three thicknesses necessary for destructive interference? nm nm nm Additional Materials
