Light of wavelength 652 nm in air undergoes constructive interference when it is perpendicularly reflected from an oil spill on a plastic sheet. The refractive index of the oil is 1.24 and that of the plastic is 1.49. What is the nonzero thickness, in nanometers, of the thinnest oil film that causes such interference?
