Frequencies and Wavelengths
For VLF the min of approximately 15 kHz is given as radio waves do not propogate much under this. C is given as 300,000,000 m/s but more accurately could be given as 299,792,458 m/s.
Wavelength l = speed of light C divided by frequency f :
l = C / f
UK TV Aerial Groups
In the United Kingdom analogue frequencies are given a channel number more usually than a frequency. If you need the frequency, it's given by the equation:
fvis= 8n + 303.25
Where fvis is the frequency of the visual carrier and n is the channel number. Then you take off the 0.25
For digital the equation is:
fmux= 8n + 306
where fmux is the centre frequency of the multiplex band you're trying to get.
