Coaxial (coax) cables work well to transmit electronic signals (data or anything else). First, let's look at the construction. Coax cables are composed of a center wire that is surrounded by an insulator (or dielectric) and then the whole of the inside is surrounded by a shield (like wire braid). There is (usually) a vinyl or rubberized jacket over the whole thing. The central wire and the shield act similar to two wires in a "twisted pair" configuration. In a basic or simple model of conduction by two wires, a voltage is applied to the ends of the two wires. Current will then flow (if it can) "out" from the source on one wire, and "back" toward that source on the other. At another instant of time, current flow in the wires will be reversed. It doesn't matter if the wires are a flat pair, like in a lamp cord, a twisted pair, like in a pair for connecting a phone, or the two conductors (the center conductor and the shield) as in a coax cable. (Certainly the characteristics are different in all types of conductors. Keep it simple here....) The coax cable has some, um, quirks. But the curious reader can find out more by using the link to the article posted by our friends at Wikipedia, where knowledge is free.
What else can I help you with?
When the arrival of a beam of light at a surface?
When a beam of light encounters a surface, it can be reflected, absorbed, transmitted, or refracted depending on the properties of the surface and the angle of incidence. The interaction between the light and the surface is governed by the laws of reflection and refraction, which determine the angles at which the light will be reflected or transmitted.
How does a beam splitter work to divide a single light beam into two separate beams?
A beam splitter is a device that uses a partially reflective surface to divide a single light beam into two separate beams. When the light beam hits the surface of the beam splitter, some of the light is transmitted through and some is reflected. This creates two separate beams of light that travel in different directions.
How do beam splitters work to divide and redirect light?
Beam splitters work by using a partially reflective surface to divide a light beam into two or more separate beams. When light hits the surface, some of it is transmitted through and some is reflected. This allows the beam splitter to redirect the light in different directions.
The arrival of a light beam at a surface?
When a light beam arrives at a surface, it can be reflected, absorbed, or transmitted. The interaction between the light and the surface depends on factors like the angle of incidence, the nature of the surface, and the wavelength of the light.
How does the moon get its energy from the sun?
The moon gets energy from the sun the same way that all the other bodies in the solar system get energy of the sun. The radiation fro the sun hits it. The reason people say the moon does not give off its own light is because the light we see is the light that is shining on the moon from the sun. The sunlight is hitting that part of the moon, so we can see it, the same way we can see things when sunlight hits them on the Earth.
What is Beam of light called?
A beam of light is simply referred to as light or a light beam.
How is laser light transmitted?
Laser light is transmitted through specialized optical components such as lenses, mirrors, and fibers. These components are designed to control and guide the direction of the laser beam while maintaining its intensity and coherence. Lasers can also be transmitted wirelessly through the air in free-space communication systems.
What is another name for the beam of light that comes from a flashlight?
Another name for the beam of light from a flashlight is a "light beam" or "beam of light."
What does beams mean?
The phrase "laser beam" refers to the columnated light that is emitted by a Laser.
What is convergent beam?
a type of light, from a beam of light
What is the difference between a beam of light and a ray of light?
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
A thin beam of light is?
A ray is a narrow beam of light.
