About the same as in a vacuum - 300 million meters/second.
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.
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.

Electromagnetic waves can exist only at one speed.

Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
In air at sea level, the speed of electromagnetic waves isroughly 882 thousand times the speed of sound.

Yes. Electromagnetic spectrum waves reach your eye through the air.
