Hmm, I got that the wavelength is 500 meters.

Answer:

Wavelength of the radio wave is 500 m.

Explanation:

It is given that,

Speed of radio waves, \(v=3\times 10^8\ m/s\)

Frequency of the wave, \(f=600\ kHz=600\times 10^3\ Hz=6\times 10^5\ Hz\)

We have to find the wavelength of the radio waves. The wavelength of a wave is given by :

\(\lambda=\dfrac{v}{f}\)

\(\lambda=\dfrac{3\times 10^8\ m/s}{6\times 10^5\ Hz}\)

\(\lambda=500\ m\)

or

\(\lambda=5\times 10^2\ m\)

So, the correct option is (d). Hence, this is the required solution.
