A thin film of oil (n = 1.25) is located on smooth, wet pavement. When viewed from a direction perpendicular to the pavement, the film reflects most strongly red light at 6.40 X 102 nm and reflects no green light at 512 nm. (a) What is the minimum thickness of the oil film? (b) Let m, corre- spond to the order of the constructive interference and m2 to the order of the destructive interference. Obtain a relation- ship between m, and m, that is consistent with the given data.
