Problem

A radio transmitter emits waves of frequency

1.2\,\text{MHz}

that are found to have a wavelength of

250\,\text{m}

at a receiving station. Determine the speed of these radio waves expressed in

\text{km h}^{-1}

. a)

3.0\times10^{5}\,\text{km h}^{-1}

1.08\times10^{8}\,\text{km h}^{-1}

1.08\times10^{9}\,\text{km h}^{-1}

1.08\times10^{7}\,\text{km h}^{-1}
