Answer:The wavelength is

Explanation:Radio waves are part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of 3.00×10^{8}m/s in vacuum.

Therefore, the wavelength can be determined by the following equation:

(1)Where c is the speed of light, is the wavelength and is the frequency.

Then, can be isolated from equation 1

(2)Notice that it is necessary to express the frequency in units of Hz.

⇒

But

Hence, the wavelength is
