'''Electromagnetic radiation''' comes in many different types, although the differences between them are quantitative rather than qualitative.  This teaching aid lists the different types that are generally recognised.

Electromagnetic radiation is an Electromagnetic oscillation wave that travels at speed of visible light carries[[Quantum]]'s energy called [[Photon]]

* '''Ultra high frequency (UHF)''': Frequencies of 300MHz to 3GHz, hence wavelengths of 10cm to 1m.  This overlaps with the microwave region.
* '''Very high frequency (VHF)''': Frequencies of 30MHz to 300MHz, hence wavelengths of 1m to 10m.
* '''High frequency (HF)''': Frequencies of 3MHz to 30MHz, hence wavelengths of 10m to 100
km.
* '''Medium frequency (MF)''': Frequencies of 300kHz to 3MHz, hence wavelengths of 100m to 1km.  These are also called '''hectometric waves''' (hectometre = 100m).
* '''Low frequency (LF)''': Frequencies of 30kHz to 300kHz, hence wavelengths of 1km to 10km.
* '''Very low frequency (VLF)''': Frequencies of 10kHz to 30kHz, hence wavelengths of 10km to 30km.
