Question 7 (10 points) For a particular application, you want to apply an anti-reflective coating to glasses which will minimize reflection of green light with a wavelength of > = 530 nm. The coating's index of refraction is n_coat = 1.63, and it will be applied on glass with index of refraction n_glass - 1.80. If you want the coating to be as thin as possible, how thick should it be? (in nm)
