Final answer:
AM and FM radio are different types of radio broadcasting. AM radio had limitations and problems with sound quality and noise. AM radio was more successful than FM due to existing technology and its ability to travel long distances.
Step-by-step explanation:
AM and FM radio are two different types of radio broadcasting. AM stands for amplitude modulation, which uses changes in the amplitude of the carrier wave to transmit information. FM stands for frequency modulation, where the frequency of the carrier wave is varied to carry the information.
AM radio had several problems, including limited bandwidth and susceptibility to noise and interference. The limited bandwidth of AM resulted in poorer sound quality compared to FM. Additionally, AM signals were more susceptible to electrical interference and atmospheric noise, leading to static and poor reception.
AM radio was more successful than FM for a few reasons. One main reason was that AM technology was more established and widely used before FM was introduced. AM radios were more commonly available, and many existing radio stations were already set up for AM broadcasting. Additionally, since AM waves have longer wavelengths, they can travel longer distances and better penetrate obstacles, making AM radio more suitable for long-range transmission.
