NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined
Free Light Refraction Snell's law
------------------------------------------------- Refractive index From Wikipedia‚ the free encyclopedia In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light‚ or any other radiation‚ propagates through that medium. Its most elementary occurrence (and historically the first one) is in Snell’s law of refraction‚ n1sinθ1= n2sinθ2‚ where θ1 and θ2 are the angles of incidence of a ray crossing the interface between two media with

Wireless Power Transmission for Solar Power Satellite (SPS) (Second Draft by N. Shinohara) 1. Theoretical Background It is known that electromagnetic energy also associated with the propagation of the electromagnetic waves. We can use theoretically all electromagnetic waves for a wireless power transmission (WPT). The difference between the WPT and communication systems is only efficiency. The Maxwell’s Equations indicate that the electromagnetic field and its power diffuse to all directions. Although

The following is a project made by anonymous: INTRODUCTION The general purpose photoconductive cell is also known as LDR – light dependent resistor. It is a type of semiconductor and its conductivity changes with proportional change in the intensity of light. There are two common types of materials used to manufacture the photoconductive cells. They are Cadmium Sulphide (CdS) and Cadmium Selenide (CdSe). Extrinsic devices have impurities added‚ which have a ground state energy closer to the conduction

third and the fourth weren’t that bad. I don’t recall getting sick any other times. I did experience some side effects from radiation. The typical side effects were discoloration‚ and somewhat of a sunburn‚ as to be expected. But aside from the physical effects on the breast tissue itself‚ I was very tired. I had my radiation treatments every morning‚ and once I left radiation‚ I would go straight back to class. But during that time I started to take vitamins so that it would increase my energy. I

Professionalism is an adherence to a set of values comprising both a formally agreed-upon code of conduct and the informal expectations of colleagues‚ clients and society. The key values include acting in a patient’s interest‚ responsiveness to the health needs of society‚ maintaining the highest standards of excellence in the practice of medicine and in the generation and dissemination of knowledge. In addition to medical knowledge and skills‚ medical professionals should present psychosocial and

oscillation that ranges from 3 KHz to 300 GHz and work hand in hand with the frequency of the radio waves and the fluctuation currents that carry radio signals. Radio Frequency has different types of properties but ones that are most important are the radiation of electromagnetic waves cause by the energy in a RF current. Usually an electromagnetic wave is the main base of what is known to be Radio Technology. RF can be found emitting around conductors of electrical currents‚ they are usually not found

Examples of Radiant Energy The term radiant energy refers to energy that travels by waves or particles‚ particularly electromagnetic radiation such as heat or x-rays. Radiant energy is created through electromagnetic waves and was discovered in 1885 by Sir William Crookes. Fields in which this terminology is most often used are telecommunications‚ heating‚ radiometry‚ lighting‚ and in terms of energy created from the sun. Radiant energy is measured in joules.

of electromagnetic radiation with matter in the experiment it means it’s the usage of ultra-light to measure the absorbance of the copper sulpate. The regions of the electromagnetic spectrum immediately adjacent to the high- and low- energy extremes of the visible region are known as the ultraviolet (UV) and infrared (IR) regions respectively. Thus a quantum of UV radiation possesses more energy than one in the visible region whilst the reverse is true for quantum of IR radiation. All spectrophotometric
