Consider the interference of light incident on the structure depicted below. It is a dielectric slab of index n=1.5 and thickness t=211nm. The surfaces are coated with a thin metallic layer to increase the coefficient of reflection to r=0.95. What is the FWHM (full width half maximum) in nm of the transmission peak if plotted versus wavelength around the value found in part A. Make the same assumption of normal incidence.
