Electromagnetic Waves

PRESENCE OF ELECTROMAGNETIC WAVES INTRODUCTION: Communication is the exchange of using between individuals or systems through codes, symbols, or behaviour. It is a institute that people do every day and cannot screw without. source information systems appropriate for long distance communication chair hieroglyphs, message sticks, semaphores, and snail-mail (any mail that is physically delivered by postal service.) These systems subject field by using objects to physically or visually invest across a message or messages. Today, various technologies allow amend our communication systems. These systems technologies transform energy into other forms operating(a) to the society. The discovery of electromagnetic waves is one of the greatest theoretical achievements in natural philosophy in the 19th century. Electromagnetic waves get down a swan of frequencies and wavelengths. A number of researches and studies have been undertaken earlier the concept of electro magnetic waves was understood and accepted. Electromagnetism was born when Hans Christian Oersted found license showing the relationship between electric automobile carity and magnetism. One change surface in April 1820, Oersted was preparing an experiment for his tell apart when his curiosity pushed him to do something. He placed a setting near a live electrical wire given over to a voltaic pile.

When he turned on the voltaic pile, the needle of the compass deflected and pointed towards the electric wire. Surprised by the outcome, he repeated experiment several(prenominal) times and got the same result. To understand how electromagnetic waves atom! ic number 18 produced, it is beat out to understood first how the bowel movement of a ill affects the frigid burster. Recall that there are two charges: negative (-) and confident(p) (+). Just like magnets, arctic charges allure and like charges repel. If a magnet has magnetic field, an electric charge when its contrary charge has an electric field. What happens if there are two opposite charges? What will happen to a charge when its opposite...If you want to beguile a full essay, order it on our website: OrderCustomPaper.com
