The wavelength is the distance between two consecutive crests or troughs. The wavelength of this radio station is 416.66 m.
Wavelength:
[tex]\lambda = \dfrac vf[/tex]
Where,
[tex]\lambda[/tex] - Wavelength
[tex]v[/tex] - velocity of the wave = [tex]\bold {3\times 10^8 \rm \ m/s}[/tex]
[tex]f[/tex]- frequency = 720 kHz = 720000 Hz
Put the values in the formula,
[tex]\lambda = \dfrac {\bold {3\times 10^8 \rm \ m/s}}{720000 \rm \ Hz}\\\\\lambda =416.66 \rm \ m[/tex]
Therefore, the wavelength of this radio station is 416.66 m.
