Final answer:
FM radio tunes to electromagnetic frequencies in the range of 88 to 108 MHz using frequency modulation to carry audio information. TV audio is also broadcast using frequency modulation, but at different frequencies within the radio frequency region.
Step-by-step explanation:
FM radio tunes to electromagnetic frequencies in the range of 88 to 108 MHz. These frequencies fall in the radio frequency region of the electromagnetic spectrum. FM stands for frequency modulation, which is a method of carrying information by varying the frequency of the carrier wave.
When you live in a region that has a particular TV station, you might sometimes pick up some of its audio portion on your FM radio receiver. This happens because the audio signal of the TV station is modulated onto a carrier wave using frequency modulation, which is the same method used in FM radio.
It's important to note that although both TV audio and FM radio are broadcast using frequency modulation, they operate at different frequencies within the radio frequency region.
