X-rays are high-frequency , and thus high-energy, electromagnetic radiation. They have wavelengths ranging from 0.01 to 10 nanometres, and thus frequencies from 3×1019 to 3×1016 Hz.

Read moreHow many Hertz are X-rays?
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 10 16 to 10 20 hertz (Hz).
Read moreHow many GHz is harmful to humans?
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. 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 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 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 .
Read moreWhat is the difference between MF and HF?
Medium Frequencies (MF) designated for marine communication range between 1605 kHz to 3800 kHz and are called “t” band. High Frequencies (HF) designated for marine communication range between 4000 kHz to 27500 kHz and are called “u” band.
