How does a song fly through the air into your radio?

Static crackles on a car's AM station in a thunderstorm while FM stays crisp.

Talk about it

  • Before we test it, guess: when a storm crackles the radio, which station gets wrecked — the one hiding the song in the wave's height, or the one hiding it in the spacing?
  • Why might a tiny faraway town pick an AM station even though it crackles more?
  • Where else have you heard a radio drop into static — a tunnel, a garage, a storm?
