Just curious about the differences between AM and FM radio waves. Any info is appreciated, thanks.
FM (Frequency Modulation) and AM (Amplitude Modulation) are two different methods of encoding information onto radio waves. The main difference between them is the way they vary the frequency or amplitude of the carrier wave to convey information.
FM waves are better for transmitting music because they have a higher bandwidth, which allows them to carry more information. This makes FM radio stations clearer and less prone to interference compared to AM radio stations.
FM waves have a higher sound quality compared to AM waves. Since FM waves have a wider bandwidth, they can carry more information and therefore produce a clearer and more detailed sound. In contrast, AM waves have a narrower bandwidth, leading to a lower sound quality and more susceptibility to interference.
AM waves can travel longer distances compared to FM waves. This is because AM waves have a longer wavelength and can reflect off the ionosphere, allowing them to travel longer distances. FM waves, on the other hand, have a shorter wavelength and are more susceptible to obstacles, making them more suitable for short-range communication.
FM waves are more commonly used for commercial broadcasting. This is because FM waves have a higher sound quality and are less prone to interference, making them more suitable for broadcasting music and other types of audio content. AM waves are typically used for talk radio and other forms of speech-based communication.
