A thin film of silicon dioxide (SiO2) is coated on a glass surface to reduce reflection of light with a wavelength of 400 nm . If the refractive index of SiO2 is 1.46 and the refractive index of glass is 1.52, what is the minimum thickness of the SiO 2 film that eliminates reflection at a perpendicular angle of incidence?
