 Radio waves are created by oscillating electric currents. How many times this current oscillates per second is called the frequency, which is measured in Hz.

 It's now time to add a few more details to this story.  Here is a basic recipe for making a radio wave:

 Voila! The antenna we've made is called a //dipole//.  Assuming that its length matches the frequency of the current generator (more on this shortly), and that the antenna is high enough above the ground, you've created a radio wave.((GIF from [[wp>Dipole_antenna |Wikipedia Dipole Antenna]]))  As electrons move up and down the length of the wires, they create varying electric and magnetic fields that couple together according to [[wp>Maxwell's_equations |Maxwell's Equations]] and propagate outward in a doughnut shape.((Picture modified from [[wp>Dipole_antenna |Wikipedia Dipole Antenna]]))
