A scientist notices that an oil slick floating on waterwhenviewed from above has many different rainbow colors reflectingoffthe surface. She aims a spectrometer at a particular spotandmeasures the wavelength to be 750 nm (in air). The indexofrefraction of water is 1.33. The index of refraction of the oil is1.20.What is the minimum thickness t of theoilslick at that spot? t =_____nm Suppose the oil had an index of refractionof1.50. What would the minimum thickness tbenow? t =_____nm
