What else can I help you with?
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.
What is a carrier and how does it affect what you hear on the radio?
A carrier is a high-frequency signal that carries information on a radio wave. The carrier frequency is modulated to encode audio signals, which are then transmitted and decoded by the radio receiver to produce sound. The carrier frequency determines the station you're tuning into on the radio.
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
How is a carrier wave produced?
A carrier wave is produced by an electronic oscillator that generates a steady waveform at a specific frequency. This waveform serves as the base signal on which information is modulated for transmission in communication systems like radio and television. The carrier wave's frequency determines the bandwidth and reception quality of the transmitted signal.
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".
When a sound wave is reflected what do you hear?
When a sound wave is reflected, you may hear an echo or reverberation of the original sound. The reflected sound wave can create additional auditory cues that can affect how the sound is perceived in the environment.
