Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhat causes electromagnetic frequency?
Electromagnetic radiation is produced whenever a charged particle, such as an electron, changes its velocity —i.e., whenever it is accelerated or decelerated. The energy of the electromagnetic radiation thus produced comes from the charged particle and is therefore lost by it.
Read moreDoes electromagnetic have frequency?
Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency . Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters.
Read moreWhat is electromagnetic frequency?
Frequency is the number of cycles of a wave to pass some point in a second . The units of frequency are thus cycles per second, or Hertz (Hz). Radio stations have frequencies. They are usually equal to the station number times 1,000,000 Hz.
Read moreWhat is the frequency of gamma rays in GHz?
Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 10 19 Hz , and wavelengths less than 10 picometers.
Read moreHow do you make a THz frequency?
Broadband terahertz pulses can be generated by exciting THz-PCAs with a femto-second short pulse laser . Using a femto-second laser with ~ 100 fs optical pulse duration, terahertz pulses with their frequency content extended up to around 5 THz and an average power of a few μW can be achieved.
Read moreWhat frequency is THz?
Terahertz (THz) is a unit of measure of frequency that is equal to 1 trillion hertz (1012 Hz) . It usually refers to the frequency of an electromagnetic wave, which is a part of the electromagnetic spectrum invisible to the naked eye that lies in between the microwave and the infrared range.
