TVs receiving broadcast programming do, they just use it to produce both picture and sound; instead of just sound as an ordinary radio does.
TVs receiving cable programming don't.
TVs receiving satellite programming do, but the radio waves are in the microwave band transmitted from the satellite and received by your dish, where they are down converted via a microwave superheterodyne stage in the dish so that they are in the frequency range the TV can handle.

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.
How do AM radio and television wavelengths compare with radar?
AM radio, FM radio, television, cellphones, GPS, and microwave ovens all use radio waves that are longer than the ones used for RADAR.
How do you benefit in our everyday life with radio waves infrared rays and uv rays?
you use them for television and for fm and am
Do car keys use radio waves?
yes,they do use radio waves
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
Are Internet waves electromag?
By Internet waves, one would assume you mean WiFi. When talking about WiFi, it does not use electromagnetic waves but instead uses radio waves like your TV or radio does.

How do you people use radio waves?
Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones
How do AM radio and television wavelengths compare with radar?
AM radio, FM radio, television, cellphones, GPS, and microwave ovens all use radio waves that are longer than the ones used for RADAR.
What industrial applications have longitudinal waves?
Industries that have longitudinal waves are cell phones, radio stations, television stations, and other industries that use sound waves.
What happens is the zone of silence?
Radio and television waves do not travel- it is difficult to explain, as they can use radio in outer space- look at satellites and moon shots. There is someting in the Zone of Silence which effectively blocks all NORMAL radio and tv reception and transmission- the author Childress seems to imply there are some frequencies ( my guess secret) that are not effected by this weird, nature-imposed blackout of radio waves.
Which waves are transmitted by a television remote control device?
They most use infa red but they use wireless for the more recent technology.
Do telephones use TV waves?
Your landline carries the voice/data on copper wires. A mobile uses radio waves but they are a different frequency from that used to broadcast TV.

What humans use radio waves?
Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases
