Question 8 10 pts Suppose you have a lens system that is to be used primarily for 727-nm red light. What is the second thinnest (in nm) coating of fluorite (magnesium fluoride) that would be non-reflective for this wavelength? The index of refraction of the lens system is 1.5 and that of the fluorite is 1.38. You should round your answer to the nearest integer, do not include unit. nl air = 1 t 1 n=1.38 ng 1.5 Glass
