Why waveguides are used instead of antennas?
waveguides are used instead of coax because at the high microwave frequencies coax would radiate the signal right through its shield. waveguides do not replace antennas.
What type of Electromagnetic radiation used in optical fiber communication?
Optical fiber communication primarily uses infrared light as the type of electromagnetic radiation. This is because infrared light has a longer wavelength that is well-suited for transmitting data over long distances through optical fibers with minimal signal loss.
What was the work of Charles Kuen Kao?
Charles Kuen Kao was a pioneer in the field of fiber optics. He made groundbreaking discoveries on the transmission of light in fibers for optical communication, leading to the development of fiber-optic communication technology that revolutionized the telecommunications industry. Kao's work laid the foundation for high-speed internet and long-distance communication through optical fibers.
Which of the following is an example of optical?
Optical fiber communication, where data is transmitted through light signals along a glass or plastic fiber, is an example of optical technology.
When is it advantageous to use a circular waveguide?
Circular waveguides are advantageous when working with high-frequency electromagnetic waves, such as in microwave and millimeter-wave applications. They are more efficient in guiding and transmitting these high-frequency signals due to lower losses and higher power-handling capabilities compared to other transmission mediums like coaxial cables. Additionally, circular waveguides are often used in radar systems and satellite communication due to their ability to pass through various bends and curves with minimal signal loss.
What is the detail explanation of factors on which optical activity depends?
Optical activity depends on factors such as the presence of chiral molecules, the specific arrangement of atoms in the molecule, and the interaction of polarized light with the molecule's asymmetric structure. The extent of optical activity is also influenced by the concentration of the chiral molecule in solution and the path length of the light passing through the sample. Ultimately, these factors determine the magnitude and direction of optical rotation exhibited by a substance.
Is optical medium and optical density same?
No, optical medium and optical density are not the same. Optical medium refers to the material through which light propagates, such as air, water, or glass. Optical density, on the other hand, is a measure of how much a material can refract or absorb light, which affects how light passes through it.
When was First optical communication used?
The ancient greek lit signal fires on hilltops to relay news of the fall of troy. Though fundamental research was carried through, it did not draw the attention until 1960 when T. Maiman invented the Laser. In 1880, Bell invented photophone whereby he can be attributed for the use of 1st practical scheme for optical communication. I would say, the journey of optical communication begets from 1970. By K. Ashique Ahmed Rafi
Was there ever any speed close to the speed of light?
Are you asking "Did any object ever move at nearly the speed of light ?" ? Electric current moving through wires, radio signals moving through cables or waveguides, and light-wave signals moving through optical fibers, travel at 0.6 to 0.95 the speed of light. Particle accelerators in Physics research accelerate subatomic particles inside gigantic magnetic rings to 0.99999 the speed of light.
Explain the propagation of light through optical fiber and appilication of optical fiber as wave guide and sensor?
Light propagates through optical fibers through the principle of total internal reflection, where the light is entirely reflected within the core of the fiber. Optical fibers act as waveguides by confining and guiding the light within the core, allowing it to travel long distances without significant loss. In sensors, optical fibers can be used to detect changes in the surrounding environment by measuring variations in the light transmitted through the fiber, offering advantages such as high sensitivity, immunity to electromagnetic interference, and remote sensing capabilities.
How data travels through wire?
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. for more information, go here- http://en.wikipedia.org/wiki/Fiber-optic_communication
What is marginal rays?
Marginal rays are the light that passes through an optical system that is away from the optical axis.
