After a rainy day, you notice several oil spots on the parking lot appear to have a rainbow on top of them. Some oil floats up on top of a puddle and spreads out to produce a thin film of oil on top of the water. The brightest spots appear red and it looks like your rainbow is missing green. Oll has anmae of refraction of 1.40 and water has an index of refraction of 1.33. Draw a diagram of the thin film of oil on top of water, Label the index of refraction for each layer in your drawing. Draw the two rays that interfere (one reflected off the top surface of oll and one reflected off the bottom surface of oil), For each reflection, indicate whether there is a phase change upon reflection. a. b. What is the thinnest layer of oil on top of water that produces constructive interference for 710 nm red light? What is the thinnest layer of oil on top of water that produces destructive interference for 550 nm green light? C.
