A thin plastic coating with a refractive index of 1.27 is applied to a glass surface with a refractive index of 1.53. When looking at the glass, the reflected light appears to be a specific color with a wavelength of 550 nm. (a) Find the smallest possible thickness for this coating. (b) What is the fırst wavelength for which this coating acts as an anti-reflection coating?
