How do Radio waves travel from the station to our radios?
Chike – Radio waves move through the air exactly the same way light waves do. They just go through it. Like light, they move in straight lines, and some materials can cause them to be reflected (or bounce). Also like light, there are some materials that can absorb radio waves. But while light is absorbed by many materials, radio waves can go right through most of the things around us (like light goes through clear glass). So when the radio waves leave the radio station, they are sent off in every direction, skittering and bouncing all the way to your radio antena, going right through any trees, walls, etc. that might be in the way.
