Answer:

0.0167 m

Explanation:

f = Frequency = 18 GHz

c = Speed of light = [tex]3\times 10^8\ m/s[/tex]

When the speed of the wave is divided by the freqeuncy we get the wavelength

Wavelength is given by

[tex]\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{18\times 10^9}\\\Rightarrow \lambda=0.0167\ m[/tex]

The wavelength of the radio waves is 0.0167 m
