The carrier wave carries the information that you hear. It is modulated by the sound which varies its amplitude or frequency. Without the carrier there would be nothing to vary so you would hear nothing.

Each radio station broadcasts on a specific frequency called a carrier wave.?
true
Why radio waves are modulated even though they have high frequency?
A radio wave is strictly a carrier of information. The modulation is necessary to convey the information, speech, music, data, etc. Sometimes a radio wave can carry information by its presence or absence. If the radio wave is present, it means one thing. If it is not present, it means another.
What type of wave carries signals for radio and television program's?
Communications Satellites ************************ Electro-magnetic waves. Carrier waves.
What is meant by am in radio?
Amplitude Modulation- AM standard Broadcast band. AM is an abbreviation for amplitude modulation,a form of radio transmission in which the carrier radio wave's amplitude is varied according to the strength of the modulating signal(sense).
How is it possible that you hear radio broadcasts with no radio?
any time objects resonate with a radio signal's frequency you have the makings of a crude radio. If those objects react in a way that allow the changes of the radio signal to make noise, you'll hear the audio. This happens when pipes, tape measures, air ducts, electrical and phone wires, are near the same length as a broadcast radio wave. The changes in the radio signal, or modulation, can get passed into other objects through corrosion between pipes, phone wiring, light fixtures and blubs, rain gutters and roofs, exhaust pipes and water heaters, furniture and floors, and so on. Generally, it only happens within a mile or so of a high power AM tower.
To get information into its carrier wave every radio station has to amplify the carrier wave.?

What is difference between modulated wave and carrier wave?
Carrier Wave: A carrier wave is a high-frequency electromagnetic wave that is used as the "carrier" or the base signal in a modulation process. It is typically a pure sine wave with a constant frequency and amplitude. The carrier wave by itself does not carry any information; it serves as a vehicle to carry the information from one location to another. In AM and FM radio broadcasting, the carrier wave is the primary signal transmitted by the radio station. Modulated Wave: A modulated wave is the result of combining the carrier wave with an information signal, such as an audio signal or data. Modulation is the process of varying the characteristics of the carrier wave (either its amplitude or frequency) in accordance with the information signal. There are two common types of modulation: Amplitude Modulation (AM) and Frequency Modulation (FM). In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. The modulated wave contains the information that needs to be transmitted, and it can be demodulated at the receiving end to retrieve the original information.
What is the meaning of suppressed carrier in am?
radio an amplitude-modulated wave in which only the sidebands are transmitted, the carrier being removedhttp://dictionary.reference.com/browse/suppressed+carrier+modulation

What does a radio wave transform radio waves into?
Sound.More informationAfter a modulated carrier signal has been received through the radio's aerial, the radio de-modulates it to release the live sound as picked-up from microphones in the radio studio (or was taken from recordings), which was then used to modulate the carrier signal at the transmitter.De-modulation that is done by a radio receiver can be described very simply as "removing the carrier signal to produce the sound".

What is the 'carrier' in the EM spectrum?
The carrier could be light, radio waves, almost any of the wave energies in this spectrum that are not hazardous to life. When used to convey information they are called carriers because one or more characteristics of the wave are varied to encode the information. One of the simplest forms of encoding or modulating a carrier is amplitude modulation which is used to make radio frequencies carry sound. The amplitude of the radio frequency signal is varied in step with the sound.
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 is the meaning of modulated wave?
Modulation is where an electronic signal (base) is combined with another electronic signal (carrier).The base could be audio, video or digital. The carrier is the frequency that a receiver (radio or television) is tuned to.The modulated wave is the result of this combination.
