|frequency in gigahertz||GHz|
|frequency in megahertz||MHz|
|frequency in chilohertz||kHz|
|frequency in hertz||Hz|
|wavelength in meters (one cycle)||lambda m|
|wavelength in inch (one cycle)||lambda in|
|wavelength in foot (one cycle)||lambda ft|
For these functions, the conversion between frequency and wavelength is valid for electromagnetic waves that travel at nearly the speed of light.
The acoustic waves propagate at the speed of sound which is subject to variations due to the air density in turn influenced by altitude, temperature and humidity.
