The process of adding information onto a bare radio wave is called "modulation".
It means changing something on the wave ... either its amplitude, frequency, or
phase, or actually turning it on and off ... according to a pattern that the transmitting
person and the receiving person have worked out and agreed to, so that when the
transmitting person makes changes to the wave, the receiving person can figure out
what those changes mean.

What type of wave carries signals for radio and television program's?
Communications Satellites ************************ Electro-magnetic waves. Carrier waves.
What is one example of a radio wave?
-- AM radio -- FM radio -- TV (non-cable) -- TV (satellite) -- police radio -- firetruck radio -- ambulance radio -- sheriff's radio -- highway patrol radio -- taxi radio -- garage-door opener -- pilot's communication -- pilot's navigation -- Blue tooth -- cellphone -- wireless Internet in the house -- iPhone -- Wifi around town -- microwave cooking -- microwave communication -- weather radar -- cellular phone -- GPS signals
How do you communicate with astronauts if radio waves are reflected back to earth?
Radio signals at frequencies up to roughly 40 to 60 MHz are absorbed or reflected from the ionosphere. At higher frequencies, the signals easily penetrate the ionosphere and continue on into space. This is the reason that AM radio (1 MHz) and "short-wave" broadcasts (4-13 MHz) are often received from great distances, but TV (54 MHz and up) and FM radio (100 MHz) are not.
What form of electromagnetic waves are used in tv signals?
It depends what you mean by TV wave. If you mean the transmission of television signals, then yes. An electrical signal can be transmitted from about 10kHz, so fits into the low end of the electromagnetic spectrum. The frequency for TV carrier signals will vary around the world, but they're typically VHF and UHF, so from 30MHz to 3GHz. Of course, digital systems and satellite distribution mean higher frequencies - in the microwave spectrum (higher frequency than light).
AM radio signals are?
Amplitute Modulation signals. a modulation(mixing)method used in early radio transmissions.in many countries, radio transmissions below 30 Mhz,are still using this method.short wave,medium wave transmissions,and some extent of VHF transmissions are possible in this method.
Is a microwave a type of infrared wave?
yes so is am fm radio and tv signals

What electromagnetic wave is used in radio and television?
The radio wave I believe.
Radio waves carry what from a station to your home?
Radio = sound wave T.V. = light wave [and sound from the speakers <33] That is completely wrong. Radio and television signals are both sent by RADIO WAVES.
What type of wave is used to transmit broadcast tv signals?
radio waves learning about this in science class it is actually interesting to tell you the truth
What type of electromagnetic wave does radio receive?
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.
Why might radio signals also be called radio waves?
A radio signal is essentially an electromagnetic wave in the radio section of the electromagnetic spectrum. Therefore, the radio signal is made of a radio wave.

What type of electromagnetic wave is used for TVs?
Radio 'waves'.
