Radiowaves

  • Low frequencies of 3kHz to 300GHz
  • Long wavelength of 1mm to 100km
  • Speed of radiowaves = 300 000 000 m/s in vacuum
  • Speed, Frequency and Wavelength of wave related by the following equation speed (m/s) = frequency (Hz) x wavelength (m)

Microwaves

  • Low frequencies between 300 MHz to 300 GHz
  • Corresponding wavelengths of 1mm to 1m
  • Speed of microwaves in vacuum = 300 000 000 m/s
