How does the optical fiber work?

Answer 1

optical fibre use the phenomenon of total internal reflection.In optical fibres glass of high refractive index is coated with a thin layer of glass of lower refractive index .the rays of light entering through its one end strickes the interference between the 2 glass surfaces at an angle greater than critical angle .this ray will be totally reflected along the whole length of fibre. light can thus travel the length of fibre and emerges from its another end without loss of intensity.

Answer 2

Well, there are lenses that help us see near and far. These are concave and convex. Concave lenses are curved inward on both sides (like a cave) and convex lenses have both sides curving outward. Concave make you see things smaller and convex make you see everything bigger.

Answer 3

Optical switches are a technology that operates on fiber optic lines to work similar to traditional electrical switches. There are two kinds of optical switches: slow switches which are operated by mechanical means which physically move an optical fiber. These are used as long-term routing solutions if there is a fault in the line. Fast switches are operated using magnetic technology to do logic operations (computations) on the optical lines.

Answer 4

Light travels through optical fibre with the phenomena of total internal refraction

in zigzag motion
