If you live in a region that has a particular TV station, you can sometimes pick up some of its audio portion on your FM radio receiver. Explain how this is possible. Does it imply that TV audio is broadcast as FM?

The Electromagnetic Spectrum is a diagram of the electromagnetic spectrum. The electromagnetic (EM) spectrum encompasses all types of electromagnetic radiation. Radiation is defined as energy that travels and spreads out as it does so; for example, visible light from a bulb in your home and radio waves from a radio station are both examples of electromagnetic radiation.

We know that if a frequency hits the antenna of the radio, the receiver is configured to resonate. So, when a signal from a frequency within the range hits the antenna, the sound is produced.

If a TV station is present in my area, we may hear a sound from the radio when a portion of the signal sent by the TV station that is within the range of the radio receiver hits the antenna. This does not imply that audio from television is carried on FM.

Therefore, this does not imply that audio from television is carried on FM.
