= Frequency Range =

The Frequency ranges of radio are broken into several bands that are named and
standardized. They appear below

| Name | Abbreviation | Range | Notes |
---------------------------------------
| Very Low Freq     | VLF | 3khz - 30khz   |                                   |
| Low Freq          | LF  | 30khz - 300khz |                                   |
| Medium Freq       | MF  | 300khz - 3mhz  | AM Radio                          |
| High Freq         | HF  | 3mhz - 30mhz   | Shortwave, 10m to 1m              |
| Very High Freq    | VHF | 30mhz - 300mhz | VHF TV, FM radio, 1000cm to 100cm |
| Ultra High Freq   | UHF | 300mhz - 3ghz  | UHF TV, 3G/4G, 100cm to 30cm      |
| Super High Freq   | SHF | 3ghz - 30ghz   |                                   |
| Extreme High Freq | EHF | 30ghz - 300ghz |                                   |

To calculate a wavelength from a frequency 

WL = c / f

Where WL is wavelength,
c is speed of light (3 * 10^8 m/s)
f is frequency
