Question: (a) A particular silica glass waveguide is reported to have a loss coefficient of 0.050 dB/cm (power out/power in, defined in Problem 19-22) for 514-nm-wavelength

(a) A particular silica glass waveguide is reported to have a loss coefficient of 0.050 dB/cm (power out/power in, defined in Problem 19-22) for 514-nm-wavelength light. The thickness of the waveguide is 0.60 Î¼m and the length is 3.0 cm. The angle of incidence ( i in the figure) is 70°. What fraction of the incident radiant intensity is transmitted through the waveguide?

(b) If the index of refraction of the waveguide material is 1.5, what is the wavelength of light inside the waveguide? What is the frequency?
