Radio waves are among the largest wave and have a fairly large range. Most are the size of a football field or building. Some of the largest are used when communicating with submarines, called ELF or Extremely Low Frequency and the distance between peaks can be miles long

Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
Radio telescope, usually a microwave dish with a movable parabolic reflector.
Radio waves have low energy compared to other types of electromagnetic waves.

AM radio waves and radio waves in general are both electromagnetic waves used for transmitting information through the air. The main difference is that AM radio waves have a lower frequency and longer wavelength compared to other radio waves. This allows AM signals to travel longer distances but with lower audio quality compared to higher frequency radio waves.
One distinctive characteristic of radio waves is their long wavelength compared to other types of electromagnetic waves. This allows radio waves to travel long distances and penetrate obstacles like buildings and clouds.

A radio telescope uses an antenna and receiver to detect radio waves emitted by astronomical objects. These telescopes are essential for studying objects that emit radio waves, such as pulsars, quasars, and radio galaxies.
