Electromagnetic waves and human health electromagnetic waves and human health, electromagnetic waves vitaliy zhurbenko, intechopen, doi: 105772/16343 available. Electromagnetic waves are defined as: waves which requires no medium for transmission and which rapidly propagates through vacuumradio waves,television waves,x-rays light rays etc,are the examples of em waves. Electromagnetic radiation is one of the many ways that energy travels through space the heat from a burning fire, the light from the sun, the x-rays used by your.
Light is not the only example of an electromagnetic wave other electromagnetic waves include the microwaves you use to heat up leftovers for dinner, and the radio waves that are broadcast from radio stations an electromagnetic wave can be created by accelerating charges moving charges back and. This video describes some of the qualities and uses of different waves on the electromagnetic spectrum for more information on gcse physics visit https://rev. Radio waves are a type of electromagnetic radiation, as are microwaves, infrared radiation, x-rays and gamma-rays the best-known use of radio waves is for communication television, cellphones. Chapter 24 | electromagnetic waves 863 figure 244the apparatus used by hertz in 1887 to generate and detect electromagnetic waves an rlc circuit connected to the first loop caused sparks across a gap in.
Tour of the electromagnetic spectrum infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with. Many of our electrical home appliances use electromagnetism as a basic principle of working if we take an example of an electric fan, the motor works on the principle of electromagnetic induction do you know that a kind of electromagnetic radiation have the potential to kill cancer cells. A radar system consists of a transmitter producing electromagnetic waves in the radio wave range or microwaves domainin these days modern radars are used in different field using radio waves or microwaves according to the programed goal,such astronomy,air traffic control. Microwaves, radio waves, and other types of radiofrequency radiation this is sometimes referred to as the electromagnetic spectrum man-made rf radiation is.
In this article, we describe two possible applications of low-intensity non-ionizing electromagnetic fields (emf) for the treatment of malaria and cancer, respectively in malaria treatment, a low-intensity extremely-low frequency magnetic field can be used to induce vibration of hemozoin, a super-paramagnetic polymer particle, inside malaria. A wireless network uses radio waves, just like cell phones, televisions and radios do in fact, communication across a wireless network is a lot like two-way radio communication here's what happens: a computer's wireless adapter translates data into a radio signal and transmits it using an antenna. Electromagnetic waves are transverse waves their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel all electromagnetic.
One of the most common uses of infrared rays is for wireless communication, such as with garage door openers, car-locking systems and handheld remote controls for televisions and other appliances since all objects emit some degree of infrared radiation, night-vision devices make use of their. Radio waves: mobile phones mobile phones use microwave energy we know • medical physicists use all parts of the electromagnetic spectrum to diagnose and treat. Because the electric field portion of the electromagnetic wave arerapidly attenuated in water, due to its conductivity this is also why light becomes horizontally polarized when itreflects off.
Electromagnetic waves and their uses - free download as word doc (doc / docx), pdf file (pdf), text file (txt) or read online for free. Final thoughts on electromagnetic radiation the fact is we are bombarded by emfs from numerous technological devices in use today, but we don't really know enough about these emfs impact the human body.
Electromagnetic radiation (which includes radio waves, light, cosmic rays, etc) moves through empty space at the speed of 299,792 km per second sunshine is a familiar example of electromagnetic radiation that is naturally emitted by the sun starlight is the same thing from suns that are much. The electromagnetic spectrum encompasses both natural and human-made sources of electromagnetic fields frequency and wavelength characterise an electromagnetic field in an electromagnetic wave, these two characteristics are directly related to each other: the higher the frequency the shorter the wavelength. Spectroscopy is used to study the interactions of electromagnetic waves with matter other technological uses are described under electromagnetic radiation contents.
