Question

A particular radio station broadcast radio waves at 100MHz (100 million Hz) if radio waves travel travel at the speed of light (300 million m/s then what is the wavelength of the radio waves that the station is broadcasting

Answer 1

The relationship between wavelength (λ), frequency (f), and speed (c), is given by


`\lambda= (c)/(f)`

So the wavelength here is


`\lambda= (3 * 10^8)/(1 * 10^8)=3m`
