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.

Q. Define roentgen and activity and Curie? One roentgen (1R) is described as the quantity of radiation which produces 1.6 × 10 12 pairs of ions in 1 gram of air. The activi
Phase advancers: Phase advancers are used to better the power factor of induction motors. The low power factor of an induction motor is because of the fact that its stator winding
Describe Gauss' law and its importance. Use it to search out the electric field due to a linear and infinite sheet charge distribution and also describe why Gauss' law cant be used
Describe the variation of the radius of bright fringe of Newton's rings with refractive index of the thin film enclosed between the glass plate and plan-convex lens when observed b
"The volume of needed mass of gas at fixed pressure is directly proportional to the Kelvin's temperature of the gas".
It determines the probability of an electron occupying a state at an energy level E. This takes into account that a collection of electron must obey the Pauli Exclusion Principle.
