A thin film of soap with n = 1.40 hanging in the air reflects dominantly red light with λ = 664 nm. Now this film is on a sheet of glass, with n = 1.55. What is the wavelength of the light in air that will now be predominantly reflected?
To keep unwanted light from reflecting from the surface of eyeglasses or other lenses, a thin film of a material with an index of refraction n = 1.38 iscoated onto the plastic lens (n = 1.55). What is the thinnest film that will minimize reflection for λ = 550 nm, the middle of the visible-light spectrum?
A 750 nm red light is not reflected in air by a thin film deposited on glass. If the thickness of the film is 150 nm and glass has a refractive index of 1.44, what is a possible value of the index of refraction of the thin film?
