The wavelength of a wave is given by the formula:

wavelength = speed of light / frequency

where the speed of light is approximately 3 x 10^8 m/s.

Substituting the given frequency of 3 x 10^9 Hz, we get:

wavelength = (3 x 10^8 m/s) / (3 x 10^9 Hz) = 0.1 meters

Therefore, the wavelength for radio waves with frequency 3 x 10^9 Hz is 0.1 meters.

So the answer is option A: 1 x 10^-1 m.
