An anti-glaring uniform thin film of magnesium fluoride (MgF2, index of refraction 1.38) covers a crown glass case of refractive index 1.52. This film has a thickness such that it cancels normally incident light of wavelength 525 nm that strikes the film surface from air. The film is thicker than the minimum thickness to achieve this cancellation. Over time, the MgF2 film wears away at a rate of 2.10 nm per year. What is the minimum number of years before...

Two identical horizontal sheets of glass have a thin film of air of thickness t between them. The glass has refractive index 1.40. The thickness t of the air layer can be varied. Light with wavelength λ in air is at normal incidence onto the top of the air film. There is constructive interference between the light reflected at the top and bottom surfaces of the air film when its thickness is 700 nm. For the same wavelength of light...
