(10%) Problem 8: A thin layer of oil with index of refraction ng = 1.47 is floating above the water. The index of refraction of water is My = 1.3. The index of refraction of air is na = 1. A light with wavelength 1 = 525 nm goes in from the air to oil and water. ಗ್ಯ a n 25% Part (a) Express the wavelength of the light in the oil, ig, in terms of i and no- A 25% Part (b) Express the minimum thickness of the film that will result in destructive interference, tmin, in terms of 1o. A 25% Part (c) Express Imin in terms of A and no- 4 25% Part (d) Solve for the numerical value of tmin in nm.
