Nonreflective coatings for camera lenses reduce the loss of light at various surfaces of multi-lens systems, as well as preventing internal reflections that might mar the image. Find the minimum thickness of a layer of magnesium fluoride (n = 1.38) on
flint glass (n = 1.66) that will cause destructive interference of reflected light of wavelength ? = 550 nm, a wavelength which is near the middle of the visual spectrum.

Brewster's Angle: When unpolarized light from air (with refractive index 1.00) strikes a piece of glass with index of refraction 1.80, the reflected light is found to be completely polarized when the angle of incidence is equal to Brewster's angle. What is the angle of refraction in this case?
