Super High Frequency (SHF): 3-30 GHz Given their ability to carry enormous amounts of data, super high frequency waves are used for relaying broadcast programs (STL/TSL/TTL), radar (weather, etc.), satellite communications and satellite broadcasting, and other applications .
Read moreWhat is extremely high frequency used for?
Extremely high frequency (EHF) waves can carry an enormous amount of data and find wide application in radar, simple-type terrestrial communications, and satellite communications .
Read moreWho gave electromagnetic wave theory?
About 150 years ago, James Clerk Maxwell , an English scientist, developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves.
Read moreWhat is Maxwell’s electromagnetic wave theory?
In his formulation of electromagnetism, Maxwell described light as a propagating wave of electric and magnetic fields . More generally, he predicted the existence of electromagnetic radiation: coupled electric and magnetic fields traveling as waves at a speed equal to the known speed of light.
Read moreWhat are the characteristics of electromagnetic wave theory?
The inherent characteristic of an electromagnetic wave is its frequency . Their frequencies remain unchanged but its wavelength changes when the wave travels from one medium to another. Electromagnetic wave follows the principle of superposition.
Read moreCan humans make electromagnetic fields?
Electromagnetic fields can be both natural and made by humans . Natural electromagnetic fields are present in the Earth. While they may be invisible, electrical fields are based on the build-up of electric charges in the environment.
Read moreWhat happens when you are exposed to electromagnetic fields?
Possible health effects Exposure to low frequency fields that are strong enough can lead to dizziness, seeing light flashes and feeling tingling or pain through stimulation of nerves . Exposure to radiofrequency fields that are strong enough can lead to heating of body tissue, and result in damage to tissues and organs.
