1,000,000,000 Hz = 1,000,000 kHz = 1,000 MHz = 1 Ghz

 

 a 1 Hz wave is
300,000 km longa 1 kHz wave is 300km longa 1 MHz wave is 300m longa 1 GHz wave is 30cm long

 

The lower the frequency, the longer the wavelength. The shorter the frequency, the shorter the wavelength.

 

All electromagnetic waves travel at the speed of light.
