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 mean by lateral shift? Derive a mathematical expression for lateral shift produced by a parallel sided glass slab for oblique incidence.
The electric field E because of a point charge at any point near it is explained as where q is the test charge and F is the force acting on it. What is the physical significance of
The stress at which the specimen breaks or reptures ultimately is known as ultimate strength. We also called this TENSILE STRENGTH .
In a non-uniform magnetic material, these substances move from stronger parts of the field to the weaker parts.why?
Assume a hot system at temperature T placed in an environment at a lower temperature T0. The system emits more radiation than it absorbs and cools down whereas the surrounding abso

Surface Imperfection: These are two dimensional and refer to a region of distortions that lies around a surface having a thickness of a some atomic diameters.
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
