Why does every radio station have a different carrier frequency?

That's not exactly true. Any frequency you choose has several radio stations on it,
but just not in the same city.
Frequency is what your radio uses to separate the individual stations. If two stations
in the same city transmitted on the same frequency, your radio couldn't separate them.
When you tuned to that frequency, you'd hear both of them at the same time, and you
couldn't understand either one.
Listen to the 27 MHz 'Citizen's Band' some time.

To get information into its carrier wave every radio station has to amplify the carrier wave?
False.
If the frequency in AM does not change then how are these sidebands formed?
The process of changing the amplitude of the "carrier" so as to add information to it (modulation) doesn't change the frequency of the carrier. But it does create energy at two other newfrequencies.The new frequencies are equal to (carrier frequency) plus and minus (the modulating frequency). These are referred to as the upper and lower sidebands.The upper sideband is an exact copy of the modulating signal, but with every component of it shifted up by an amount equal to the carrier frequency. The lower sideband is a mirror image of the upper sideband, with every frequency component in it reflected about the carrier frequency.
What is the frequency and wave form of old land line phone carrier?
First answer.The landline phone has no carrier frequency it is a baseband signal with a 3KHz bandwidth.Correction:So there is a signal that can handle a 3KHz bandwidth, what do you call that signal? I call it a carrier, if you don't have a carrier, you will need to amplify the audio every 30 meters else you will end up with no audio at the end of the line. So there is a carrier on all phone lines. Note the carrier signal are up to 90 VPP and is AM modulated at the instrument, but in digital systems the carrier are switched on and of, FSK modulation.
Need of modulation in communication?
Need for modulation: 1. Length of the antenna for a transmitter is inversly proportional to the frequency of the signal to be transmitted. So we try shift the frequency of the singal for the transmission to higher frequencies. 2. Every transmission of signal in a bandwidth is assigned with a particular frequency which is attained by modulating the signal with the carrier frequency. Different modulation techniques are implemented according to the requirements and compatibilities
What is the frequencies in the range of RF waves used by commercial radio broadcasting stations?
Each country has different frequency bands allocated for AM and FM radio. In the U.S. AM takes up the range from 535KHz to 1605KHz. FM radio takes 88.0MHz to 108.0MHz.Each radio station then receives a slice of that frequency band, regulated by the FCC. Each station is typically given a frequency far from all other stations. For example, three stations would be given the frequencies 93.3MHz, 94.5MHz and 96.1MHz. In theory, the stations could be closer (ie 94.3MHz, 94.5MHz and 94.7MHz) though this is rarely done because each station would then cause more interference to its neighbors.(The stations don't actually 'cause interference' to their neighbors. The weaknessis the ability of consumer-grade receivers to separate stations whose frequenciesare close together.)

What is the frequency of color?
Every color has a different frequency. That's why it appears to our eyes as a different color.
What wavelength is Jazz FM?
There was a UK station Jazz FM which broadcast on the FM frequency 102.2 which launched on March 4, 1990 but was changed to 102.2 Smooth FM in 2005. There is a current UK station called Jazz FM which is a digital station broadcasting over the internet.

What frequency is Radio Disney on FM mhz?
Yes Am 550 No it's not. It's on Am, but every city has a different channel. One station may be Am 550 and another station is Am 990. Go to RadioDisney.com to find out the station in your city. 1250 is also another.
Does the Traxxas Rustler xl5 come in 2 different bodyshells?
Yes, there is a different color for every frequency.
How is a radio signal transmitted and received?
A broadcasting radio station has to generate and transmit (send out) carrier signals from its transmitters. A carrier signal has to be used because it is impractical to send out sound waves of energy over the very long distances used for radio broadcasting. If, for example, a station broadcasts on a radio frequency of 455 kHz, before it is transmitted by the station's radio transmitters, that carrier signal first has to be modulated with the sounds coming from the station's studio. The modulation method used can be either amplitude modulation (AM), frequency modulation (FM) or digital (DAB). DAB is short for "digital audio broadcasting". At the radio receivers used by the station's listeners, the modulated carrier signal is received through their aerials and then has to be de-modulated to release the studio sound. De-modulation can be described very simply as "removing the carrier signal to produce the sound". That sound then has to be amplified so that it can be listened-to using loudspeakers or headphones. The actual carrier frequencies used by a particular station have to be varied: 1) to suit their transmitters' locations 2) to suit the areas to be covered by that station's broadcasts and 3) to avoid causing interference with other radio stations. In every country there is a government agency which controls the particular frequencies which can be used by each station that broadcasts in that country. The fair use of all the frequencies available for broadcasting worldwide is co-ordinated and administered by part of the United Nations organisation - the ITU (International Telecommunications Union) - and its members are representatives from all countries worldwide.
How do you reach pune railway station to akurdi?
1. use local trains runs from pune to akurdi. frequency every 45 mins. 2. use city bus. hadapsar-pune. from BJ medical college station. every 30mins.
Is color related to the frequency of a visible light wave?
Yes. Every different frequency (wavelength) of light is perceived as a different color by the human eye. Except in colorblind people, that is.
