White light with a wavelength range of 350 - 700 nm is incident from air (n = 1.00 onto a thin film. The film has air on one side and a material of a higher refractive index on the other, as per the image below. Air nair = 1.00 Thin film nfilm Unknown material n > nfilm Figure. Thin film is between air and a material with a higher refractive index than the thin film. Part 1) What is the refractive index of the thin film if the minimum thickness is 130 nm and there is constructive interference in the wavelength range given? n = White light Part 2) What is the wavelength of 519 nm light (i.e., this is the wavelength of the light in air) in the film? An = Part 3) If the film was now suspended in air, as shown below, what would be the minimum thickness of the film needed for constructive interference for the wavelength range given above? Air Mair = Air nair Thin film film nm White light 1.00 1.00 Figure. The thin film from earlier parts is now suspended in air. t = nm White light with a wavelength range of 350 - 700 nm is incident from air (n = 1.00 onto a thin film.
