[[Image:RadioWaves.jpg|right|thumb|Diagram of the electric (E) and magnetic (H) fields of Radio Waves emanating from a radio transmitting antenna (small dark vertical line in the center). Radio waves are usually produced by electric current alternating at radio frequency flowing in a special purpose conductor, called an antenna. [[Antenna (radio)|Antenna]] dimensions must generally be comparable to wavelength to work efficiently. Very long waves are not practical because of the enormous antennas needed to produce them, although they are sometimes produced by lightning. Radio waves are also produced by [[radio astronomy|cosmic phenomena]] in deep space. Actually, any kind of reciprocating motion of electric charges or magnets can produce radio waves if it is fast enough. Although very impractical, even a person waving a charged stick very fast can produce faint radio waves.]]
ഏതാണ്ട് 10<sup>-3</sup> മീറ്ററില്‍ കൂടുതല്‍ തരംഗ ദൈര്‍ഘ്യം ഉള്ള വിദ്യുത്കാന്തിക തരംഗങ്ങളാണ് റേഡിയോ തരംഗങ്ങള്‍ എന്നു അറിയപ്പെടുന്നത്‍. വിദ്യുത്കാന്തിക വര്‍ണ്ണരാജിയില്‍ ഏറ്റവും കൂടുതല്‍ തരംഗദൈര്‍ഘ്യൈം ഉള്ളതും ഇതിനാണ്.
