Nature of EM Waves & Wave Equation

If frequency of electromagnetic wave is $60\text{ MHz}$ and it travels in air along $z$ direction then the corresponding electric and magnetic field vectors will be mutually perpendicular to each other and the wavelength of the wave (in $\text{m}$ ) is:

Show answer and solution

Answer: (b)

$\lambda = \frac{c}{\nu}$ .
$\lambda = \frac{3\times 10^{8}}{60\times 10^{6}} = 5\ \text{m}$ .
So the answer is (b) 5.
