super low frequency (ELF 2 ), ITU band no.2, megameter waves

300 - 3 kHz

ultra low frequency (ULF), ITU band no.3

3 - 30 kHz

very low frequency (VLF), ITU band no. 4, myriameter waves

30 - 300 kHz

low frequency (LF), ITU band no. 5, kilometer waves

0.3 - 3 MHz

medium frequency (MF), ITU band no. 6 hectometer waves

extremely high frequency (EHF), ITU band no. 11, millimeter waves

300 GHz- 3 THz

part of micrometer waves, includes part of thermal infrared, ITU band no. 12

3 -30 THz

part of micrometer waves, includes part of thermal infrared

30 -300 THz

part of micrometer waves, part of infrared

300 THz - 3 PHz

near infrared, visible, near ultraviolet

3 - 30 PHz

part of vacuum ultraviolet

30 -300 PHz

part of soft X rays

300 PHz - 3 EHz

part of soft X rays

3 -30 EHz

hard X rays and part of soft g rays

30 - 300 EHz

part of soft and part of hard g rays (limit at 510 keV)

300 - 3000 EHz

part of hard g rays and part of cosmic g rays

3000 -30 000 EHz

g rays produced by cosmic rays

The corresponding wavelength can be obtained by dividing speed of light (3´ 108m/s) by the frequency.
