This paper provides a descriptive account of the 2004 Senate campaign and an. analysis of the foundation upon which Obamaâs victory was built. In so doing, the paper. can provide some clues as to what kind of support and opposition a future Obama. candidacy may face.
An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.ptical fiber is also used in imaging optics. A coherent bundle of fibers is used, sometimes along with lenses, for a long, thin imaging device called an endoscope, which is used to view objects through a small hole. Medical endoscopes are used for minimally invasive exploratory or surgical procedures.
They do this by Total Internal Reflection. That's why optical fibers can guide light for such long distances-because the walls of the fibre don't absorb any light at all as long as the angle of incidence is greater than the critical angle. fibre optic cable is made from a glass core (or in cheaper lower grade ones-plastic) , that carries the light, surrounded by a glass cladding of lower refractive index, which reflects escaping light back into the core.
