Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects.   - North Dakota (locally ) is the 39th state of the United States, having been admitted to the union on November 2, 1889.  - A county seat is an administrative center, seat of government, or capital city of a county or civil parish.
