Page "Electromagnetic radiation" Paragraph 70

When EM radiation at the frequences for which it is referred to as " radio waves " impinges upon a conductor, it couples to the conductor, travels along it, and induces an electric current on the surface of the conductor by moving the electrons of the conducting material in correlated bunches of charge.

Such effects can cover macroscopic distances in conductors ( including as radio antennas ), since the wavelength of radiowaves is long, by human scales.

Radio waves thus have the most overtly " wave-like " characteristics of all the types of EMR, since their waves are so long.
