Explain about the double-crucible method.
Low loss fibers are mostly manufactured by using double crucible and vapour phase deposition method.
The double-crucible method is the mainly common direct melt procedure. The double-crucible process combines the molten rods in a single perform by using two concentric crucibles. Optical fibers are drawn by this molten glass by using a same fiber drawing process as into vapor phase oxidation. A demonstration of a fiber drawing apparatus by using the double crucible process is illustrated in the given figure.

What do you understand by half period zones? What is their other name? Distinguish between physical and geometric (wave) approximations of light.
Definition: The electric field in a region is shown by continues lines (also known as lines of force). Field line is an imaginary line along which a positive test charge will move
