There are seven regions in the electromagnetic spectrum which in order of lowest to highest frequency are: Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays .19 Oca 2016
Read moreWhat are 7 examples of electromagnetic waves?
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.
Read moreWhat electromagnetic frequency is harmful to humans?
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 a safe level of RF radiation?
The SAR is a value that corresponds to the relative amount of RF energy absorbed in the head of a user of a wireless handset. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg) .
