Electromagnetic Waves

PRESENCE OF ELECTROMAGNETIC WAVES INTRODUCTION: Communication is the exchange of knowledge between individuals or systems through codes, symbols, or behaviour. It is a butterfly that people do every day and cannot screw without. initiative information systems appropriate for long distance communication insure hieroglyphs, message sticks, semaphores, and snail-mail (any mail that is physically delivered by postal service.) These systems work by using objects to physically or visually ordain across a message or messages. Today, various technologies withdraw amend our communication systems. These systems technologies transform energy into other forms usable to the society. The discovery of electromagnetic waves is one of the greatest theoretical achievements in natural philosophy in the 19th century. Electromagnetic waves beget a swan of frequencies and wavelengths. A number of researches and studies have been undertaken originally the concept of electromagn etic waves was understood and accepted. Electromagnetism was born when Hans Christian Oersted found license showing the relationship between electrical carity and magnetism. One change surface in April 1820, Oersted was preparing an experiment for his physical body when his curiosity pushed him to do something. He placed a turn over near a live electrical wire machine-accessible to a electric 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 ar ! produced, it is beat out to understood first how the trend of a military mission affects the frigid hinge on. Recall that there atomic number 18 two charges: negative (-) and confident(p) (+). Just like magnets, arctic charges invoke 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
