Read moreWhat are low frequency radio waves used for?
Low to Medium Frequencies ELF radio waves, the lowest of all radio frequencies, have a long range and are useful in penetrating water and rock for communication with submarines and inside mines and caves . The most powerful natural source of ELF/VLF waves is lightning, according to the Stanford VLF Group.

Read moreWhat is extremely low frequency radiation?
Extremely low frequency (ELF) fields includes alternating current (AC) fields and other electromagnetic, non-ionizing radiation from 1 Hz to 300 Hz . ELF fields at 60 Hz are produced by power lines, electrical wiring, and electrical equipment.
Read moreIs Extremely Low Frequency dangerous?
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 medium frequency used for?
Medium Frequency (MF): 300-3000 kHz Because medium frequencies afford stable transmission of radio waves over long distances, they are used primarily for medium wave broadcasting (AM radio), ship communications, LORAN (radio navigation), and other applications .
