Radio waves can broadcast signals using two methods. In amplitude modulation (AM), the frequencies of the carrier wave are measured in hundreds of thousands of hertz. For frequency modulation (FM), the frequencies are in hundreds of millions of hertz. Which of these methods uses waves with higher energy?
1 answer
Frequency modulation (FM) uses waves with higher energy, as the frequencies are in the hundreds of millions of hertz compared to the frequencies in the hundreds of thousands of hertz used in amplitude modulation (AM). The higher frequency of FM waves results in greater energy per wave, making FM signals more powerful than AM signals.
