Solar cells are often coated with a transparent thin film of silicon monoxide (SiO, n = 1.45) to minimize re?ective losses from the surface. Suppose that a silicon solar cell (n = 3.5) is coated with a thin film of SiO for this purpose. If the thickness of the coating is 90.1 nm, Find the maximum wavelength (nm) of ultraviolet light (in air) for which the reflection will be maximized instead of minimized. (The wavelength of ultraviolet light is shorter than that of visible light.)
