AM and FM broadcasts use specific frequencies because they have been allocated by the government for radio broadcasting. These frequencies are carefully chosen to avoid interference between different stations and to optimize the transmission of signals.
The main difference between AM and FM broadcasts is that they use different frequency ranges. AM (Amplitude Modulation) broadcasts use frequencies in the range of 535 to 1705 kHz, while FM (Frequency Modulation) broadcasts use frequencies in the range of 88 to 108 MHz.
AM and FM broadcasts are at different frequencies because they use different methods of modulating the carrier wave. AM modulates the amplitude of the wave, while FM modulates the frequency. This results in different frequency ranges being used for each type of broadcast.
The frequencies used for AM and FM broadcasts have a direct impact on the quality of sound. AM broadcasts are more susceptible to interference and noise, which can affect the quality of the sound. On the other hand, FM broadcasts have a wider frequency range and are less prone to interference, resulting in better sound quality.
Yes, apart from government regulations, there are other factors that determine the specific frequencies used for AM and FM broadcasts. These include the availability of frequencies, the power of the transmitter, the geographical location, and the target audience of the station.
