The correct option is C Total internal reflection from core cladding boundary
Light remains confined within core of simple
optical fibre because of Total internal reflection from core cladding boundary.
Light is confined within the core of a simple
optical fiber by. If light hits a boundary of a material of lower refractive
index at a steep enough angle, it cannot get out and it's reflected back into
the high index medium, as in the figure below.
An optical fibre is a thin rod of high-quality
glass. Very little light is absorbed by the glass. ... Optical fibres can carry
more information than an ordinary cable of the same thickness. The signals in
optical fibres do not weaken as much over long distances as the signals in
ordinary cables.
Total internal reflection. When light traveling in
an optically dense medium hits a boundary at a steep angle (larger than the
critical angle for the boundary), the light is completely reflected. ... This
effect is used in optical fibers to confine light in the core.
The light in a fiber-optic cable travels through
the core (hallway) by constantly bouncing from the cladding (mirror-lined walls),
a principle called total internal reflection. Because the cladding does not
absorb any light from the core, the light wave can travel great distances.
