Radio

Turn the radio up! In this BrainPOP movie, Tim and Moby discuss the wonderful world of radios and how they work! You’ll discover how radio transmitters send out signals, how these signals can change individual waves, and how your radio converts all this information back into sound. Find out what “AM” and “FM” stand for and how those bands are different. Plus, see how radio waves travel from one point to another without bouncing off into space, and what the frequencies on your radio dial represent. This is one movie you’ll definitely want to tune in to!
