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 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.
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.
Do radio and television waves affect global warming?
No. Radio/television waves do not affect the temperature, but usage of radios and televisions definitely does.
Which characteristic is common to microwaves radio waves and television waves?
They are all radio waves with frequencies lower than visible light.
Do some TVs use radio waves?
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.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
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 are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How are radio and television waves added to em waves?
by changing the amplitude or frequency of the radio waves.
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.

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
Is it true that radio waves carry information from a broadcasting station t your radio or television?
Is it true that radio waves carry information from a broadcasting station to your radio or television
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.
Are radar waves visible?
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
Do radio and television waves affect global warming?
No. Radio/television waves do not affect the temperature, but usage of radios and televisions definitely does.
