Like all other electromagnetic waves, radio waves travel at the speed of light in vacuum. They are generated by electric charges, like electron undergoing acceleration and deceleration such as time varying electric current in a conducting wires.
Radio waves can be produced by rapid acceleration and deceleration of electrons in aerials (conductors). These can be detected by receivers of aerials.
The frequency range of the Long radio waves is a few Hz to a MHz.
And, \(1MHz=10^6Hz\)
So, the correct answer is Option-long radio waves, a few Hz to a few MHz.
