    Answer: How Do Radio Waves Work?

    Blackbody Radiation. A blackbody is an object that absorbs, then re-emits, radiation.

    Free-Emission Radiation. When electrons in gas atoms become dislodged or stripped, they are ionized.

    Spectral Line Emission. The third type of thermal emission is spectral line emission.

    Synchrotron Emission. This is a non-thermal form ...

    Explanation:Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is 10,000 km. Like all other electromagnetic waves, radio waves travel at the speed of light in vacuum. They are generated by electric charges undergoing acceleration, such as time varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects.
