Light from an aquarium (Fig. 9.27) goes from water (n = ) through a plane of glass

Light from an aquarium (Fig. 9.27) goes from water (n = ¾) through a plane of glass (n = 3/2) into air (n = 1). Assuming it's a monochromatic plane wave and that it strikes the glass at normal incidence, find the minimum and maximum transmission coefficients (Eq. 9.199). You can see the fish clearly; how well can it see you?
