Microwaves are low on the electromagnetic spectrum. The electromagnetic spectrum is a range of all the possible electric radiation. Frequency of a wave is the number of waves per second and the frequency of a microwave is between 300 MHz and 300 GHz. The wavelength of a wave is the distance from one peak of a wave to the peak of a following wave and a wavelength of a microwave varies from one millimeter to thirty centimeters. The frequencies range from ultra high frequency to super high frequency
different types of media forms on wired communications and they all do a different job. Wireless Technologies could be satellite links or Radio communication. They all have good and bad points to discuss. Wired Technology could include twisted pair, Fibre optic or broadband over power lines. Wireless communication has transformed the way we communicate to each other.
The enigma of Backbone has been with us for over 30 years since Peter Laurie first referred to the use of microwave relay towers in his 1967 Sunday Times article on civil defence. Three years later he expanded the article into the groundbreaking "Beneath The City Streets" in which he says "The GPO planned a chain of concrete towers code-named Backbone which
it’s procrastination or stubbornness or raw fear, but there’s a reason we only just now got rid of our microwave, which made its first spectacular appearance in our lives in 1991. I remember the day my mother, finger wagging, told us of the dangers of opening the door while the microwave was still running. Her point was not that it would be harmful to us, but rather that it would hurt the microwave, as though after being opened mid-cook, it would simply lose the will to go on. “I’m sorry,” it would
engineering construction in the Toronto area. This resulted in a number of buildings rising over hundreds of feet. In order to solve this problem, a tower was built to rise above all of these buildings and stop the problem with communications. With the microwave towers rising to over 338m, and the antenna rising to the top of the ... ... middle of paper ... ...quished ownership from 1997 to Jan 2004. The TrizecHahn Corporation took control over it in order to perform a 26 million dollar expansion for
telephone and the nearest base station is achieved by the microwave emissions from the antenna. Concerns have been raised about the type of mobile telephone that has the antenna in the handset. In this case, the antenna is very close to the user's head during normal use of the telephone and there is concern about the level of microwave emissions to which the brain is being exposed. Media reports have claimed that up to 2/3 of the microwave emissions from hand- held mobile telephones may be absorbed
safe location when the time is necessary. Radar, stands for Radio detection and ranging. Radar transmits microwaves in a focused beam. The microwave energy bounces off of its primary object and returns as data to be measured (Weather Questions 1). Radar then will send pulses of energy, rather than a continuous signal, which it will then measure how far away the object was when the microwaves reflected off of it. Combined with the radar's ability to scan up and down and in a circular motion which
The transmission of words, sounds, images, or data in the form of electronic or electromagnetic signals or impulses. Transmission media include the telephone (using wire or optical cable), radio, television, microwave, and satellite. Data communication, the fastest growing field of telecommunication, is the process of transmitting data in digital form by wire or radio. Digital data can be generated directly in a 1/0 binary code by a computer or can be produced from a voice or visual signal
nothing.” according to Jack Welch. So the government has decided to take a closer look at high powered Micro waves. In his paper I‘m going to speak to you about high power microwaves, it’s applications, a comparison of two different types, some of the history, and the findings in results of its research. “High power microwaves (HPM) is an imprecise term used by several communities [1]. In the DoD it pertains primarily to the generation of high peak power bursts of narrowband (coherent) electromagnetic
The Voice of the Sea in The Awakening Many different symbols were utilized in Kate Chopin's The Awakening to illustrate the underlying themes and internal conflict of the characters. One constant and re-emerging symbol is the sea. The voice of the sea is seductive, never ceasing, whispering, clamoring, murmuring, inviting the soul to wander for a spell in abysses of solitude; to lose itself in mazes of inward contemplation. The voice of the sea speaks to the soul. The touch of the sea

Like other things on Serendip, the paper is not intended to be "authoritative" but is instead provided to encourage others to themselves learn about and think through subjects of interest, and, by providing relevant web links, to serve as a "window" to help them do so. Web links were active as of the time the paper was posted but are not updated. There's a standing joke in our family, or rather between my sister and I. It usually comes up at family get-togethers, about the time that we're all
be slower, mentally, then people who can speak fluently. Although research has made some progress in diagnosing the causes of stuttering, people still have preconceptions about stutterers. There are new studies being done to find genetic and neural links to explain and perhaps help cure this potentially isolating disorder. One of the problems that stutterers face in society is the fast pace that people talk. When trying to talk in public, people will often try and finish a sentence for someone who
The Link between Sports and Success in Death of a Salesman and Fences Sports have become one of the most dominant elements in society. Today sports are an integral part of lifestyle, entertainment and leisure. Sports have become an outlet for success and prestige. The recurring emphasis on sports appears in both Arthur Miller’s Death of a Salesman and August Wilson’s Fences. While Death of a Salesman portrays sports as a means to popularity and subsequent success, Fences portrays sports negatively
An Analysis of Shakespeare's Sonnet 116 Shakespeare's Sonnet 116, denying Time's harvest of love, contains 46 iambic, 15 spondaic, 6 pyrrhic, and 3 trochaic feet. Like the varying magnitudes of stars that distinguish the sky's constellations, infused with myths describing all degrees and types of love, the spondaic, trochaic, and pyrrhic substitutions create a pattern of meaning that can be inferred by the discerning eye and mind. Shakespeare emphasizes his denial of the effects of Time on love

Creativity Creativity is the sole heart of modernization, technology and the arts. Without creativity, humanity would still thrive in caves. There is no argument against creativity being an important aspect of our society, there is, however, a question whether creativity is spawned by mental disorder. Albert Einstein came up with ideas that seemed impossible or eccentric. Froyd's psychology theorems were laughed at, but now widely used and accepted. Both men were highly successful with their
initiated the development of the NSFNET which, today, provides a major backbone communication service for the Internet. With its 45 megabit per second facilities, the NSFNET carries on the order of 12 billion packets per month between the networks it links. The National Aeronautics and Space Administration (NASA) and the U.S. Department of Energy contributed additional backbone facilities in the form of the NSINET and ESNET respectively. In Europe, major international backbones such as NORDUNET and others
search began the night I received this assignment. I went to the search engine we all know and use so well, Yahoo, and began my search from there. When I typed in the words beer pong into the search box, I received almost two hundred thousand related links. I became even more pleased with this result, knowing that there was so much to tell. Eventually I came across a catching site, known as the National Beer Pong League. There is something of this nature that exists? I wondered so I clicked. Since
performances, a practice employing period instruments and small all-male choral ensembles(Wilson). When Christmas season roles around, everyone can count on hearing Handel’s own personal favorite The Messiah. This is the kind of song we need, something that links us through common knowledge and feeling, past and present. Handel combines the sheer grandeur and power of his German roots with the color of his Italian experience, joining this with the unique flavor of the English language(Alexander). His music
