What is the modern uses of refraction of light?
it is used in optical fibres for data transmission.
Which types of electromagnetic waves can be used to send signals along optical fibers?
Only light is used to send signals along optical fibres. That's why this type of fibre is described as "optical". Fibres designed to conduct electrical signals are referred to as "wires".
Which product is manufacturedin the MCVD process?
Optical Fibres. To know more, look up Silicon tetrachloride.
Why doesn't light escape from the sides of an optical fiber?
optical fibres are made out of materials with high refractive index, this ensures that the light is always reflected back inside the fibre..
Is it possible to make a product of fiberglass transparent?
No ,only translucent, the chopped fibres of glass scatter the light preventing optical clarity.
How have optical fibers led to the use of visible light?
There seems to be some confusion here! Visible light was being used - to see things, for example - millions of years before optical fibres were invented!
Where does this optical fibres are used?
Optical fibers are used both in medical and telecommunication purposes. Optical fibres are able to convey 100% of the light waves so they are used for seeing the internal organs of your body. Since they can transmit electromagnetic signals with such efficiency they are used for communications like underground cable and telephone wires.
Why are optical fibers often called light pipes?
light can be trapped by total internal reflection inside a bent a glass rod and 'piped' along a curved path,A single very thin glass fibre behaves in the same way. if several thousand such fibres are trapped together a flexible light pipe is obtained that can be used, for example, by doctors as an 'endoscope', to obtain an image of an internal organ in the body, by engineers to light up some awkward sport for inspection.the latest telephone 'cable' are optical (very pure glass) fibres carrying information as pulses of laser light.
What has the author P D M Barrett written?
P. D. M. Barrett has written: 'The use of optical fibres in short distance communication'
Anvantage of optic fiber?
Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. Higher carrying capacity - Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same cable or more channels to come through the cable into your cable TV box. Less signal degradation - The loss of signal in optical fibre is less than in copper wire. Light signals - Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. This means clearer phone conversations or TV reception. Digital signals - Optical fibres are ideally suited for carrying digital information, which is especially useful in computer networks. Non-flammable - Because no electricity is passed through optical fibres, there is no fire hazard. Lightweight and thin - An optical cable weighs less than a comparable copper wire cable. Optical fibres can be drawn to smaller diameters than copper wire. Fibre-optic cables take up less space in the ground.
What is the role of cotton in making artificial fibers?
the role of cotton in making artificial fibres, it makes the fibre more flexible and smooth. Water absorbent.
What are the descending fibres of projection fibres?
They include = cortico-spinal fibres + cortico-bulbar fibres + cortico-pontine fibres + cortico-rubral fibres + cortico-striate fibres
