A.m. waves have a wavelength of approximately 100 m. FM waves have a wavelength of approximately 1 m. Which one has a higher frequency? Which one has higher energy?
The frequency of a wave is inversely proportional to its wavelength. Smaller wavelengths correspond to higher frequencies.
Since FM waves have a wavelength of approximately 1 m, they have a higher frequency than AM waves with a wavelength of approximately 100 m.
The energy of a wave is directly proportional to its frequency. Therefore, FM waves, which have a higher frequency, have higher energy compared to AM waves.
