If you have ever wondered how you get to see and hear. how stuff like cell phones, microwave and remote-controled toys work, you need to learn Electromagnetic Spectrum, Wavelength And Frequency to understand.\nIf you are not curious, they are not important.

Simply because microwave radiations impart energy to atoms and molecules in the crystal structure. Materials which can withstand the induced extra energy are safe, others are not.

If it'smade from iron materials the electromagnetic wave will be absorbed by the iron and the signale in teh phone will be so bad

All kinds of electromagnetic radiation reflect as light.\nSo do microwaves.\n\nTh

Yes, a radio wave is an elecromagnetic wave just as light, X-rays, microwave, gamma rays, etc.  All carried by photons.  Radio waves are the least energetic, or longest wavelength, of the electromagnetic spectrum.  Sound waves, on the other hand, are like waves in water, or sand dunes-they are movements of atoms-air, in the case of sound-they are not carried by photons, do not go the speed of light, and are not electromagnetic.  All electromagneic waves go the speed of light, since they are carried by photons.  The only difference between a radio wave and a visible light wave in the frequency of the wave and the energy of the photon (both of which are integrated).

Microwave is the back bone of many of the distant multiple telephone svc. the wide band satellite service is the link to tie the world together. Tv & telephone service. The radiation doecnt cause any real health problems as the beams are very direct as a beam of light. It is a lot of our world communications.

I checked out those links.  It looks like a bunch of BS to me.  (FWIW, I have a BS in Physics with 33 graduate hours in Physics and a Masters in Science Ed.)\n\nFirst, the facts:  Electromagnetic Fields (EMF) are produced whenever electric charges are in motion, i.e. in all electrical devices.  Light rays are one form of EMF's.  We already know how to protect against those: Wear sunblock.  \n\nBut the EMF's that we're talking about here are radio frequency EMF's, which are much lower on the spectrum, and thus have much less energy.  The EMF's that have caused concern in the medical field are Extremely Low Frequency radio waves such as those produced by power lines.  When electricity is moving down the lines, oscillating back and forth 60 times a second, it sends off these low frequency radio waves.  Some epidemiological studies have associated long term exposure to these ELF radio waves with childhood leukemia.  This is still controversial, however, and the US EPA has not issued any official position about EMF exposure.\nIn any event, with power lines we're talking about constant exposure to relatively high (1 mG) EMF's.  You wouldn't get that from your home computer unless you parked yourself within 4 inches of it for 24 hours a day.  Remember, EMF's drop off in intensity as the square of the distance, e.g. doubling your distance reduces them by a factor of four, tripling the distance reduces them by a factor of nine.\n\nAnyway, the only real way to shield something from low frequency EMF's is to completely enclose it in a metal box or wire mesh.  These things are essentially versions of what physicists call a Faraday Cage.  The idea is that the metallic condutors absorb the EMF's so they don't penetrate the cage.  Radio engineers protect sensitive radio equipment this way.  Security experts do the same thing the other way around.  Radios, TV's and even computers and electric typewriters produce minute radio waves that can be picked up by very sensitive receivers, so to prevent spies from finding out what's going on in sensitive government sites, they shield them in metallic conductors.\n\nThe device your links show clearly does not surround you, so it can't be effective in shielding from EMFs.  All the talk about sympathetic oscillations is true but meaningless.  Any piece of metal does that; that's how antennas work.  An antenna is just a piece of metal; when a vibrating EMF hits the antenna, the electons start to vibrate in synch with it.  IOW, you could get the same result as these devices claim by just wearing a piece of metal on your chest.  The claims about blood flow, "healthy energy states", etc. are just nonsense.

One of the four forces in nature is the electromagnetic force.  A sub-aspect of this is the qualities of electromagnetic radiation.  What is electromagnetic radiation?  It's every form of energy radiation on the electromagnetic spectrum such as:\nmicrowaves -- get a quick meal, transmit information using microwaves as a carrier wave like cell phones and satellites do.\nradio waves -- pretty much everyone knows what a radio is and has one.\nX-rays -- medical diagnosis would be lost without them.\nUse of the magnetic force also allows for things in the medical industry such as MRI and CT scans....that whole nuclear medicine field.\nThe flow or movement of particles called electrons is studied by physicists.  The flow or current of electrons is also known as electricity.  Lots of people use that for various things.\nIn a fundamental sense, everything is made up of atoms.  \nThe atomic and sub atomic world is the purview of the field of study called quantum physics.  So, EVERYTHING is influenced by physics in a sense.

They are alll electromagnetic waves.  They all have different frequencies.  Radio waves have the lowest and gamma rays have the highest.

According to Maxwell's laws, one type of field can induce the other and vice versa. This makes electromagnetic waves possible.

i think no because if waves did effect the body then you should use wireless phones or t v antennas or radio

heat is not electromagnetic radiation, it's molecular kinetic energy (or thermal energy).  The sun emits Ultraviolet radiation, amongst other emissions in the light spectra, but i don't believe the heat emitted can be attributed to an electromagnetic wave.

Electromagnetic waves are non-mechanical waves that are composed of electric waves and magnetic waves, both products of electric and magnetic fields. They are able to propagate through space (without medium) due to the dependence of electric fields to magnetic fields and vice versa. Electric fields serve to reinforce magnetic fields and they, in turn, reinforce electric fields. This reinforcement is the reason why electromagnetic waves can travel space without a medium.

Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.\n\nThe term electromagnetic radiation is also used as a synonym for electromagnetic waves in general, even if they are not radiating or travelling in free space. This sense includes, for example, light travelling through an optical fiber, or electrical energy travelling within a coaxial cable.\n\nElectromagnetic (EM) radiation carries energy and momentum which may be imparted when it interacts with matter.

Microwaves are not ionizing radiation, but they will cause your flesh to cook if you are exposed to enough of it for long enough. They will cause burns.
