... index of refraction of 1.5 and the clad has an index of refraction of 1.485. To protect the clad fiber, it is typicallyenclosed in some kind of protective rubber or plastic jacket. This type of ... characteristics of the lens, and the contours of each grovecan be figured using this equation. C and K will depend on several factors, such asthe desired focal length, the index of refraction, and the ... kinetic energy of electrons is a function of the materialtemperature. However, in different materials, energies and densities of free electronsare not the same. When two dissimilar materials at...
