Sometimes a nonreflective coating is applied to a lens, such as a camera lens. The coating has an index of refraction between the index of air and the index of the lens. The coating cancels the reflections of one particular wavelength of the incident light. Usually, it cancels green-yellow light (λ 546.0 nm) in the middle of the visible spectrum. (a) Assuming the light is incident perpendicular to the lens surface, what is the minimum thickness of the coating in...

A thin coating of Magnesium Fluoride (MgF2) is deposited on the surface of some eyeglasses which have an index of refraction of 1.6. The MgF2 has an index of refraction of 1.38. (a) What is the minimum thickness of the coating so that green light of wavelength 500 nm has minimal reflectance (i.e. maximum transmission for anti-reflective coating)? (b) What is the minimum thickness of the coating so that green light of wavelength 500 nm has maximum reflectance?

1. We want to make a thin film coating we can apply to the outside of a glass window that will cancel (or at least significantly reduce) infrared light (heat) from getting into a house or car during the summer. Assume that the wavelength of this light is 1=2000 nm, the index of refraction of the air is n=1.00, the film is n=1.75 and the glass is 1.55. nm a. What minimum thickness of the film is needed? This film...
