A thin film of polystyrene is used as an antireflective coating for fabulite (known as the substrate). The index of refraction of the polystyrene is 1.49, and the index of refraction of the fabulite is 2.409. (Figure 1) Part A What is the minimum thickness of film required? Assume that the wavelength of the light in air is 470 nanometers. Express your answer in nanometers.

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...

8. Visible light has wavelengths between about 1 = 400nm on the violet end of the spectrum to about l = 700nm on the red end. An anti-reflective coating with index ne = 1.2 forms a thin film on the surface of a glass lens with index n, = 1.5. (a) For a wavelength in middle of the visible-wavelength range (which appears green), find the minimum thickness of the coating for dark reflections of light entering the lens from the...

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?
