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.
Double Crucible Fiber drawing process
If a hydrogen atom in its ground state absorbs a photon with a wavelength of 93 nm, it jumps to an excited state. What is the value of the energy in that excited state?
How are appliances we use in the domestic circuit interlinked? What are the benefits of this connection?
