Your radio signal is a paved road with speed bumps. AM is how big each speedbump is. FM is how many speed bumps you hit in a mile.

Your radio is a car suspension that is tuned to handle bigger and smaller speedbumps, or it’s tuned to handle more or fewer speedbumps in a mile. When properly tuned for a particular size of speedbumps, your AM radio is able to interpret the sound of that road. When properly tuned to the number of speedbumps, your FM radio is able to interpret the sound of that road. When neither are properly aligned, the sound of the road is all over the place…(static).
