Electromagnetic Radiation and Electron

The purpose of this research paper is to demonstrate how much Wireless Technology has really improved, since the year James Clerk Maxwell developed and explained the theory of electromagnetic waves on 1865; And Heinrich Hertz put into practice Maxwell 's theory by experimenting with electromagnetic waves-measuring their speed and wavelength between the years 1885-1889; Until present days. As this type of technology grows, it is perceivable to what extent people have learned how to manipulate electromagnetic waves at will. For the purpose of this paper, I have done a very extensive research looking for remarkable improvements that would take a substantial and detailed portion that would explain the what, when and how of each major breakthrough, on the body of this research.

Otherwise their static. No one believed Maxwell, and Hertz set out to prove Maxwell right. Hertz used two rods to serve as a receivers. When the applied a spark to one of the rods, he could get it to jump to the other rod. Hertz discovered how to make the electric and magnetic fields separate themselves and travel freely.

Where A is the amplitude, λ is the wavelength, v is the wave speed, t is the time elapsed, and (x,y) is the displacement of the wave.

When you think of radio waves what comes to mind? Do you imagine invisible vibrations traveling through the atmosphere? Maybe you imagine a wireless communication where people can send messages from one place to another. What most people may not imagine, though, is a feud between two men, both of whom have been, at some point in their lives, linked to the birth of radio. Despite Guglielmo Marconi being long attested as the inventor of the radio, “the U.S. Supreme Court voided four of Marconi’s key patents, belatedly acknowledging Tesla’s innovations in radio” (History.com 2009). In the book The Representation of Science and Scientists on Postage Stamps Christopher B. Yardley notes that “Tesla developed the means to reliably produce radio frequencies, publicly demonstrated the principles of radio, and transmitted long distance signals” (157). With history finally rectifying the injustice to Tesla, the world has started recognizing his achievements in the field of radio transmission. In the Netflix documentary David L Goodstein, Professor of Physics at California Institute of Technology, indicated that “Tesla was the one with the real vision” and “his vision describes the world that we live in” (Tesla: Master of Lightning 2000) Still today people play with radio-controlled motor boats; however, the use of remote control technology is not limited to hobby toys.

The wavelength is the horizontal distance between successive crests (or troughs), and the period is the time required for two successive crests to pass a given point.

Use available evidence to suggest reasons for the differences in range of electromagnetic radiation detected by humans and other animals

“The wavelength is 0.20s”. It’s wrong, because 0.20s is the wave’s period not its wavelength. Wavelength is length of one complete vibration and its unit is (m).

If you go into account why a quite cave and you yell, you may hear your voice coming back to you. That's what the radar machine does. It Emmett emits that radiowave just like your yell, and it interprets the waves when they bounced back to the machine. A radio wave is no electromagnetic radiation. All radars have four main parts; the antenna, the indicator (which is a display screen), The transmitter, and the receiver. These parts are used in the cycle. The cycle starts with the transmitter. The transmitter amidst the way. The waves can travel for miles and when it reaches the target, the wave Downs is back to the radio system and is detected by the antenna and get sent to the receiver. The receiver then take the information and it Hanses it. The information is commonly displayed on the screen called the indicator that displays the data. Most indicators are ppi indicators, also known as Plan Position Indicators. This is virtual map that has in the center of the location of the radar and will display the target according to its proximity to the radar system. The position of the target is called

Electromagnetic fields, or EMFs, is sometimes referred to as radiation. We are exposed to EMFs almost all the time. Almost all of the electronics or powered devices have some sort of electromagnetism in them. This includes your cell phone, kitchen appliances, television, lights, and computer. Electric door bells also use electromagnetic fields. When the button is pushed it signals for the coil to get electrified, then the bell sounds all because of the electromagnetic force.

Radio waves, a form of electromagnetic radiation, have had a significant impact on our daily life because of their use as a form of communication. Radio waves have long wavelengths and have low energy photon particles. Because they have low energy photons, they have lower frequencies when compared to other forms of electromagnetic radiation, such as x- rays that have a higher frequency despite having short wavelengths. Today, radio waves are used as a method to transmit and receive information. Technology that makes use of radio waves includes telephones, television and more popularly known the radio, which picks up signals from a radio antenna that is equipped with a resonator that filters the signals received and as its name implies it resonates only with radio waves of a certain frequency; this allows people to listen to different sounds at different frequencies. Radio waves can be emitted by objects in space, such as planets, while radio waves that occur on Earth can come from lightning.

FM is a technique in which the instantaneous frequency of the carrier wave is varied according to the instantaneous amplitude of the modulating signal. In other words if the amplitude of the modulating signal increases, then there will be a corresponding increase in the frequency of the modulated wave, similarly if the amplitude of the modulating signal decreases, then there will be a corresponding

The basis of wireless power transfer occurs between a handful of phenomena that have been discovered by scientists recently. Magnetism is something that we have been exposed to since early

Wavelength: The wavelength is the distance from one point on a wave to the same point on the next wave along. We can measure the wavelength of a wave from one peak of a wave to another. One wave length can be seen or described as the distance between to peaks or troughs of a wave. Equation- v = d/T therefore… d = v x T (m)

A higher frequency of light causes higher energy electrons. 4. The amount of current that flows is dependent upon the intensity (brightness) of the light. Prior to the 1900’s light was considered to be wave-like in nature. This was due to the success of Maxwell’s Electromagnetic Theory.

Simply it can be said that the power radiated or received by the antenna is the function of angular position and radial distribution from the antenna [24]. In the fig.24 [9] below we can see the side view of the rectangular Microstrip element associated with source, and also the radiating of E fields.
