A layer of synthetic diamond is grown on a quartz substrate inside a vacuum chamber. The refractive indices of the substrate and the diamond layer are ns = 1.54 and nd = 2.42, respectively. A laser beam with wavelength ?0 = 633nm is used to measure the thickness of the layer by illuminating it through the substrate and observing the resulting interference on a screen.
What is the thickness t of the thin film of diamond?
