PLEASE HELP THANK YOU

Answer : The wavelength of the radio waves is

Explanation : Given,

Frequency =

Wave speed =

As we know that the speed of a wave is related to its frequency and wavelength.

Formula used:

where,

is the wave speed in metres per second, (m/s )

f is the frequency in hertz, (Hz )

is the wavelength in metres, (m)

Now putting all the given values in the above formula, we get:

Therefore, the wavelength of the radio waves is
