The wavelength (λ) of a wave is related to the frequency (f) of the wave by the equation: v = f λ where v is the speed of the wave. The speed of radio waves in air is 300 000 000 m/s. Use this equation to calculate the wavelength of the carrier waves used by radio stations Triple M, Melbourne, and 3CV, Bendigo.

The highest common factor of 132 and 220
