A uniform film of TiO2, 1036 nm thick and having index of refraction 2.62, is spread uniformly over the surface of crown glass of refractive index 1.52. Light of wavelength 600 nm falls at normal incidence onto the film from air. You want to increase the thickness of this film so that the reflected light cancels.
What is the minimum thickness of TiO2 that you must add so the reflected light cancels as desired?
After you make the adjustment in part (a), what is the path difference between the light reflected off the top of the film and the light that cancels it after traveling through the film? Express your answer in nanometers.
Express your answer in wavelengths of the light in the TiO2 film.

A soap film (n = 1.33) is 498 nm thick and lies on a glass plate (n = 1.52). Sunlight, whose wavelengths (in vacuum) extend from 380 to 750 nm, travels through the air and strikes the film perpendicularly. For which wavelength(s) in this range does destructive interference cause the film to look dark in reflected light? To 3 significant figures

A plastic film of refractive index 1.6 is applied to the surface of a car window to increase the reflectivity and keep the car's interior cooler. The window glass has index of refraction 1.54. What minimum thickness is required if light of wavelength 526nm in air reflected from the two sides of the film is to interfere constructively? Give your answer in nm with two digits after the decimal.
