5. Consider the reflectance R from tin of light with wavelength 2 = 589.3 nm. The index of refraction of tin is complex, with the real n and imaginary n2 parts at this wavelength given by 1.50 and 5.30, respectively. That is, = n1 + in2 = 1.50 +5.30 i. (a) Determine and plot (on the same graph) the reflectance R as a function of incident angle in both s- and p-polarized light. Note that the Fresnel reflection coefficients will be complex whenever the index is complex. Reflectance is a real quantity given by the absolute value of the Fresnel coefficient squared R = \2. (b) Discuss interesting points. Is there a Brewster's angle? Explain. 5. Consider the reflectance R from tin of light with wavelength 2 = 589.3 nm.
