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 are the maximum and minimum frequency of radio waves?
Radio waves have a frequency range that typically spans from about 3 kHz (kilohertz) to 300 GHz (gigahertz). The minimum frequency of 3 kHz corresponds to the very low frequency (VLF) range, while the maximum frequency of 300 GHz falls within the extremely high frequency (EHF) range. This broad spectrum allows radio waves to be utilized for various communication technologies, including AM and FM radio, television, and wireless networks.
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 range of frequencies of radio waves?
the frequency range of radio waves is ranging from 3kHz-300GHz
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.

Why does the sound quality from a radio set degrade when lightning strikes near the radio set?
A lightning strike contains a broad range of electromagnetic radiation, from the low infrasonics, right to above the UHF radio range. The light is caused by the electrical flow ionizing the air, which gives the E-M spectrum. The ionized path also excites the electrons of the atmospheric molecules and they emit light. The emitted EM radiation will interfere with the signal being received by the radio. AM radio is affected more, as the receiver is sensitive to changes in amplitude of a frequency. A lightning strike has lots of amplitude and covers all frequencies. FM radio is less affected. The FM receiver is sensitive to changes in frequency in order to change the amplitude of the Audio Frequency. A static charge during a thunderstorm, can build up on an aerial. This is sometimes heard as a loud crackling on an AM receiver. As soon as the lightening happens, the crackling stops, as the charge has been removed. This is known as 'precipitation static'.
What is the relation between carrier frequency and modulating signal?
If the modulating system is AM (Amplitude Modulation) then the amplitude of the carrier wave changes with the amplitude of the modulation. On a specrum analyser that shows up as frequency sidebands. If the frequency of the carrier waves depends on the amplitude of the modulating signal that is called FM (frequency modulation). On a spectrum analyser that shows up as sidebands also.
