Unformatted text preview: 3. Under what conditions of incident angle and refractive index is the incident beam fully reflected when light travels across two different materials? 4. The core of optical fibers is made of a drawn fiber of SiO 2 . a.) Describe one type of i) chemical impurity ii) physical defect that could be problematic to the efficiency of transmission and explain how each would be disruptive. (Hint: We are not looking so much for specific impurities as an explanation of what type of impurities might be problematic and how their presence would be disruptive.) b.) One advantage of fiber optics is that the fibers can transmit light of many different energies. Are there any limitations on possible energies for transmission?...
