A highly reflective mirror can be made for a particular wavelength at normal incidence by using two thin layers of transparent materials of indices of refraction nl and ni (1 < nj < n2) on the surface of the glass (n > n2)' What should be the minimum thicknesses d, and d2 in Fig. 34-29 in terms of the incident wavelength A, to maximize reflection
