Any radio signal, regardless of its frequency, can be amplitude-modulated in order to
add information to it.
In the US, commercial broadcast AM radio stations operate on carrier frequencies
between 540 KHz and 1.7 MHz.

What does the number of a FM radio station mean?
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the signal.
What are diffrence between AM radio waves and FM radio waves?
AM stands for "Amplitude Modulation". The sound signal you hear is transmitted by modifying the amplitude of the carrier frequency.FM stands for "Frequency Modulation". The sound signal you hear is transmitted by modifying the carrier frequency itself.AM uses a 5Khz bandwidth with additional space to allow for signal separation avoiding interference between stations.FM requires a wider bandwidth.AM has lower sound quality and is subject to static from weather conditions and adjacent frequency radio transmissions.FM has wider bandwidth per channel, due to the better ability to separate noise in the FM bandwidth.AM has a longer range than FM and with the correct conditions can bounce a signal off the ionosphere allowing for longer range possibly causing interference with far away radio stations on the same frequency.FM signals line of site only and will drop of after about 50 miles from the station as the earth curves away. To compensate for this, broadcasting stations use high transmission antennas.
What frequency does radio waves use?
Radio frequency (RF) is a rate of oscillation in the range of about 30 kHz to 300 GHz
What is the radio frequency range?
freq range of rf is 3hz (extremely low frequency) to 300Ghz (extremely high frequency)
What is the main use of frequency modulation?
Frequency modulation is used to broadcast radio waves to receivers. The most common use of it is in FM radio, which contains a range of radio frequencies.
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz

What is the frequency range of radio waves that can penetrate human body?
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
What is the relation between amplitude and freq if a transmitter having frequency 500mhz what is the amplitude range if have any formula please tell me about that?
Actually the amplitude depends on your modulator by which you generated your signal you can pick any amplitude you want but here is the formula for frequency modulated signal: Ac here decide the amplitude of the signal and you can see that it is not related to the frequency component of your signal.
What is the range of frequencies of radio waves?
the frequency range of radio waves is ranging from 3kHz-300GHz

Which is a property of light waves but not sound waves?
why cannot it be both? by definition, amplititude is the extreme range of fluctuating quantity. swing range of a pendulum, current flow,bla,bla,bla. amplitude MODULATION is in reference to radio waves with regards to signal RANGE ie: AM Radio- amplitude modulation am bounces and the range of frequency is modulated within the extreme band withs of the wave.
What is the radio frequency range?
freq range of rf is 3hz (extremely low frequency) to 300Ghz (extremely high frequency)
What amplitude and frequency does a radar waves have?
Frequency is above 1 GHz or so for radar. General amplitude of waves put out by a radar gun is what I was trying to find when I stumbled across this. I imagine its in the mV or lower range though
What is the frequency range of the SINCGARS radio?
30.000 to 87.975 MHZ
