Short Wave Radio Range
833 wordsElectromagnetic radiation is defined as the emission and transmission of energy in the form of electromagnetic waves. An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves of sound, which scientists have categorized in order to depict the usefulness of the different properties. Theoretically, electromagnetic waves can be as lo...

Radio Frequency Waves
603 wordsRadio waves travel at 186,000 miles per second through air. In contrast, sound waves travel at only 1/5 of a mile per second. If a modulation is made of the radio wave that exactly reproduces the amplitude and frequency characteristics of the original sound wave, then sound can be transmitted rapidly over long distances. This leads to a very interesting phenomena. During a live broadcast in New York, the music will reach listeners in California a fraction of a second before it can be heard by th...

Radio Waves And Light Waves
2,156 wordsThe electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultravioletlight, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultravioletlight can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers of...

Frequency Of The Carrier Wave
882 wordsRadio Waves In the modern society, radio is the most widely used medium of broadcasting and electronic communication: it plays a major role in many areas such as public safety, industrial manufacturing, processing, agriculture, transportation, entertainment, national defense, space travel, overseas communication, news reporting and weather forecasting. In radio broadcasts, they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude m...

Radio Waves From An Antenna
764 wordsBefore beginning our research on radio waves, to us, radio waves were just waves going through the atmosphere, carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves, and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves, which represent voice and other soun...

Part In The Transmission Of Radio Waves
1,145 wordsJargon buster 2 G 2 G, the second generation or GSM, is the technology currently used in the operation of mobile phones. 3 G 3 G, or third generation, is the generic term used for the next generation of mobile communications systems. The new systems will enhance the services available today and offer multimedia and internet access and the ability to view video footage. The third generation technology used in the UK is called UMTS. These services operate at 2200 MHz. (2.2 GHz). Aerial / Antenna A...

Faint Radio Waves
1,029 wordsIntroduction: There are many fascinating things about the universe and there are lots to learn from it too. Most of the discoveries in outer space were in our solar system and most of them were observed from the human eye aided by telescopes. Is it possible to observe objects from outer space using instruments other than the telescope? Fortunately, we are able to explore other parts of the electromagnetic spectrum using different kinds of observations such as the radio telescope, invented by Mr....
