Answer :

Final answer:

The question pertains to the differences between AM and FM radio broadcasting frequencies, where AM radio uses amplitude modulation and FM radio uses frequency modulation.

Explanation:

The subject matter of the question concerns the broadcasting frequencies of AM and FM radio stations and the principles of amplitude modulation (AM) and frequency modulation (FM). Specifically, AM radio waves carry signals in the frequency range from 540 to 1600 kHz, where the amplitude of the carrier wave is varied, resulting in a wave with constant frequency but varying amplitude.

FM radio waves operate in a higher frequency range of 88 to 108 MHz, modulating the frequency of the carrier wave, leading to a constant amplitude but a varying frequency.

Regarding the example provided, an AM radio station broadcasts at 1020 kHz by varying the amplitude of the wave to transmit information, while its FM partner broadcasts at 98.2 MHz by varying the frequency. This difference in modulation techniques characterizes the two types of radio broadcasting.
