The frequency of the radio waves from the fm station is:
[tex]f=103.1 MHz = 103.1 \cdot 10^6 Hz[/tex]
And the speed of the waves corresponds to the speed of light:
[tex]v=3 \cdot 10^8 m/s[/tex]
Therefore, the wavelength of the radio waves can be found by using the following equation:
[tex]\lambda= \frac{v}{f}= \frac{3 \cdot 10^8 m/s}{103.1 \cdot 10^6 Hz}=2.91 m [/tex]
