What my kids wanted to know

Radio waves are cousins to light and x-rays. If you streched out a light wave it would become a radio wave. If you squished it up, you'd get an x-ray. All of these waves are called electromagnetic waves.

The body doesn't feel these waves because we don't have nerves in our body to feel them. In our skin, we'd have nerves that can detect temperature (hot or cold), pressure (squeezes) and texture (sandpaper or cotton). But we don't have any receptors in our skin to pick up radio waves.

The only time you might actually feel electormagnetic waves is when they are small (which means they have more energy) and you get hot like when you stand in the sun. But that's because the waves are transfering the energy to your skin and it gets heated up. The radio waves that are around town don't have enough energy to heat you up.
