Extremely low frequency (ELF) electromagnetic waves are currently the lowest frequency waves used routinely for wireless communication .15 Nis 2003
Read moreWhat is the effect of extremely low frequency?
The issue of extremely low frequency (ELF) biological effects is very controversial. Research has focused on possible carcinogenic, reproductive, and neurological effects . Other suggested health effects include cardiovascular, brain and behavior, hormonal and immune system changes.
Read moreWhat is extremely low frequency EMF?
Extremely low frequency (ELF) electric and magnetic fields (EMF) occupy the lower part of the electromagnetic spectrum in the frequency range 0-3000 Hz . ELF EMF result from electrically charged particles.
Read moreWhat is the lowest frequency called?
The tone of lowest frequency is called the fundamental ; the others, overtones. The frequencies of the overtones may be whole multiples (e.g., 2, 3, 4, etc., of the fundamental frequency, in which case they…
Read moreWhat are very low frequency waves?
Very low frequency (VLF) is a radio frequency band in the range of 3 to 30 kHz with wavelengths from 10 to 100 km . It is also the name of the band designated by the International Telecommunication Union (ITU).
Read moreWhat is extremely low frequency emission?
Extremely Low Frequency Emission Hazards: During the 1990s, most electromagnetic frequency (EMF) research focused on extremely low frequency (ELF) exposures stemming from conventional power sources, such as power lines, electrical substations, or home appliances .
Read moreWhat is very low frequency used for?
The VLF band is used for a few radio navigation services, government time radio stations (broadcasting time signals to set radio clocks) and for secure military communication . Since VLF waves can penetrate at least 40 meters (131 ft) into saltwater, they are used for military communication with submarines.
