Your body acts like a ground a little bit. Your body is too small and does not work well. Radio Wave Electricity Radio wave electricity is electricity that radio waves make in the antenna wire. Radio waves hit the antenna something like ocean waves hit the shore. Ocean waves make water rush up and back with each wave.
Radio waves make electricity flow up and down in the antenna wire like that.
Radio wave electricity flows back and forth about a million times each second. It changes back and forth faster for a shorter distance between the waves. The detector changes the radio wave electricity into sound electricity. Radio stations make the radio waves get stronger and weaker as the sound changes. The strength of the radio waves copy the sound vibrations.
