A scientist notices that an oil slick floating on water when viewedfrom above has many different rainbow colors reflecting off thesurface. She aims a spectrometer at a particular spot and measuresthe wavelength to be 750nm (in air). The index of refraction ofwater is 1.33
a)The index of refraction of the oil is 1.20. What is the minimumthickness of the oil slick at that spot?
Express your answer in nanometers to three significant figures. innm
b)Suppose the oil had an index of refraction of 1.50. What wouldthe minimum thickness be now?
Express your answer in nanometers to three significant figures. innm
