one of a set of modes of propagation having the same exponential variation of the field components along the longitudinal axis of a uniform transmission line, but having different configurations in any transverse cross-section
optical density is the amount of light
Not quite sure what you mean; light itself IS wave.
It is the direction fibers lay in. Oriented strand board is an example. In materials like fiberglass they are at right angles to one another for strength.
Birefringence is when a material is able to refract light in two slightly different directions depending upon the angle of the light coming in. Crystals if calcite can be shown to do this.
"Elementary" in this context means that they are not known to be made up of smaller particles. It doesn't mean they can't undergo changes. You can think of the flavors as different excitation states of the same particle - comparable to different vibration modes on the same string. In fact, according to string theory (which is not really a scientific theory yet - more a hypothesis), the fundamental structures in the Universe ARE a type of string, and the different vibration modes of those strings are what gives them their different properties.
Splicing means joining in optical fibers.a process called splicing takes place to join two fibers.
A "degenerate" is someone who "borrows" another person's genes/ becomes that person.
interchanged; distorted; degenerate Changed.
No, "degenerate" typically refers to a decline or weakening from a previous state. It does not mean sacred, which conveys a sense of reverence or holiness.
do you mean what do people get from fibers.......answer lies and fibs or do you mean how do people become fibers.....answer without trying or realising what they have said.
optical power means living
optical density is the amount of light
It means it has two modes.
what do mean by retting of fibres The retting of fibers is the softening and separating of fibers by moistening or soaking them.
To plait mean to braid, so plaited fibers are braided.
sight
optics deals with the behavior of light and optical deals with sight and the interaction of visible light
