How does the sped of radio wave compare with speed of tv waves when both measured in vacuum?
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.
Why does tv use radio waves?
because on the em spectrum, radio waves are the lowest. if a tv used a higher raadioactive source like uv and you were exposed to it to much (by watching to much tv) you could get cancer and die unfortunately.

What speed do television waves travel in air?
If the information for television goes through the air, the waves used are electromagnetic waves; specifically of the type called RADIO WAVES.All electromagnetic waves travel at the speed of light when in a vacuum: about 300,000 km/second. In air, the speed is almost the same as in a vacuum.
