consider an optical fiber having a core index of 1.46 and a cladding index of 1.45. a) What is the critical angle for this core-cladding interface? B) for what range of angles inside the fiber at the entrance to the fiber will light totally internally reflected at the upper edge of the fiber? C) to what range of incidence angles does this correspond? D) how will that range of incidence angles in part C be changed if the fiber is...

Refractive index of core of an optical fibre is 1.46 and its diameter is 250μm. Light propagates along the axis of the fibre . If the fibre bends at one point with radius of curvature R, Calculate the minimum value (critical radius of curvature Rmin) to sustain the light inside, without escaping from the fibre. Discuss the factors on which the critical radius of curvature may depend? Does it depend on the colour of light propagating through the fibre? ...

A particular human hair has a Young's modulus of 3.77×109 N/m2and a diameter of 146 μm. If a 256 g object is suspended by the single strand of hair that is originally 15.5 cmlong, by how much ΔL hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much ΔLAl would the aluminum stretch? If the strand of hair is modeled as a spring, what is...
