The Applications Of Electromagnetic Waves

Electrical- The study and application of electricity, electronics, and electromagnetism. These engineers will face problems such as making

One day while he was dissecting a frog hanging from a copper wire Equality 7-2521 was able to find the power of electricity which he called The Box of Glass which at that time he was exploring in his tunnel

Humanity lives in the electronic age, where everything is powered by electricity, but whom is responsible for these marvels of modern engineering and science? Many millennials tout that Nikola Tesla is responsible for the electronic age and that those credited by the history books for ground breaking inventions were thieving from Tesla, however, Alex Knapp of Forbes has a different perspective. He wrote an article titled “Nikola Tesla Wasn’t God and Thomas Edison Wasn’t the Devil”. Through several strategies and rhetorical appeals the author of “Nikola Tesla Wasn’t God and Thomas Edison Wasn’t the Devil” makes an excellent case for his argument.

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. ("The origins of radio, n.d." )

People such as Benjamin Franklin, Eli Whitney, and Samuel F.B. Morse have made life changing moments in history. Franklin introduce the idea of electricity, with his more commonly known experiment the key and kite. Though Franklin only established a connection with lightning and electricity, it lead to greater discoveries. Such as the controversy, Tesla versus Edison, and alternating currents(AC) versus direct currents(DC). With all invention there is the common theme of aiding civilization; to make diffucult tasks simpler, but we can't always predict the outcomes.

This allowed her students to visualize how fast electricity could travel in just a billionth of a

The Railroad and the Pony Express has been the only way to communicate remotely and send correspondence. Joseph Henry and Samuel F.B. Morse would sculpture the future of communication with the invention of the electromagnet and telegraph. Joseph was a graduate of Princeton (Then called the College of New Jersey) as a physicist. The fascination with electricity and magnetism in which he had read reports on from Europe fascinated his desire to research and develop an electromagnet. This shaped our future of electricity as we see it today. With the ability to distinguish between high amperage circuits and high voltage circuits, this laid the baseline for what we know today as “Inductance”. Electrical conductor produces energy by the changing of current or the changing of voltage to produce a strong magnetic force while only using a small battery. By Joseph Henry’s introduction to inductance also paved a path for the invention of electric motors. These advances in technology developed a method for illuminating homes and streets. The use of electricity was spreading almost as fast as the railroad. This improved the lifestyle and functionality of America. (Tindall, Shi

Huygens was one of the first scientists to recognize that the speed of light must necessarily be a finite quantity, and from this he was able to determine a kinematic theory of light. The theory details spherical waves which emanate at the speed of light (which Huygens did not explicitly define other than saying that it was a finite quantity) in uniform wave fronts. Huygens’ spherical light waves propagated in a longitudinal fashion, and thus must necessarily have a medium through which to propagate. Huygens envisioned this ether was “composed of tiny, closely spaced, elastic particles, which vibrate and pass on the waves of light” (Charles). However, not all of Huygens’ contemporaries agreed with his formulation of the wave nature of light. Isaac Newton, in particular, was a vocal opponent of his theory in favor of his own ‘corpuscular’ theory of light. Huygens, as stated in his Ebscohost Biography: “...regarded the transmission of such particles through empty space to be mere Newtonian “action at a distance” again and incompatible with a mechanistic view of nature”. However, Newton’s prominence at the time meant that Huygens’s theory of light remained relatively unknown until mid-19th century, when it was rediscovered and eventually reformulated into what we now know as the Maxwell

An electrical engineer is able to create, manipulate, transmit and receive data by electronic means such as 1’s and 0’s. What electrical engineers do is deal with problems associated with large-scale electrical systems such as power, transmission, and motor control. Electrical engineers deal with electrical components that can span from the earth all the way to intergalactic space. One life changing invention is that of the transistors. The transistor is small semiconductor that allows the flow of current to a source, it is able to stop or it amplify it depending on the type used. This is only one of the many remarkable inventions electrical engineers get to deal

I as an electrical engineer pursuing my master in electrical and electronic engineering developed a skill to solve the problem. During my bachelors, I studied natural and physical science and basic fundamentals that are required in the engineering field and also gained vast knowledge how to identify and tackle new problem in the practical world.

The nature of light has been the subject of contentious scientific scrutiny for most of recorded scientific history. At the heart of that scrutiny was a debate over the fundamental properties of light: is light a wave or a particle? Ancient scientists like Euclid of Alexandria and Ptolemy of Rome conducted rudimentary experiments exploring the tendency of light to reflect off of smooth surfaces or refract when passing through a medium. These were the first indications of light’s wave properties. Ultimately, this wave theory of light was insufficient in explaining all of light’s phenomena; for example, when light encounters a corner, it will cast a shadow rather than bend around the corner like waves of sound--thus the debate continued. The work of an Italian physicist, Francessco

The human race has advanced a great deal over the course of recent history, particularly so since the 18th century. Countless of these developments in society can be attributed to the achievements of engineers - however, despite this, many do not realise their contribution and importance. One of the fundamental bases behind these engineering feats is the harnessing of energy sources, such as electrical and heat energy. This has allowed for many innovations, for example power stations, transportation, communications and computers, which have all become critical to society and the modern world in which we live.

Originally electricity and magnetism were thought of as two separate forces. This view changed, however, with the publication of James Clerk Maxwell's 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments:

Hertz discovered that ultraviolet light discharged certain electrically charged metallic plates, a phenomenon that could not be explained by Maxwell’s Wave Theory. In order to explain this phenomenon termed the

Alan Francis Chalmers is an associate professor who works extensive in the history and philosophy of science (physical). Alan Chalmers has taught at the University of Sydney since 1971, first in the School of Philosophy, and from 1987 at the Unit for the History and Philosophy of Science. He attained a B.Sc. in physics at the University of Bristol, and his M.Sc. in physics from the University of Manchester. His Ph.D. on the electromagnetic theory of J.C. Maxwell was granted by the University of London. He was elected a Fellow of the Academy of Humanities in 1997. He has been a Visiting Scholar at the Flinders Philosophy Department since 1999.
