- Radio wave - Wikipedia
Radio waves (formerly called Hertzian waves) are a type of electromagnetic radiation with the lowest frequencies and the longest wavelengths in the electromagnetic spectrum, typically with frequencies below 300 gigahertz (GHz) and wavelengths greater than 1 millimeter (⁄64 inch), about the diameter of a grain of rice
- Radio wave | Examples, Uses, Facts, Range | Britannica
radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves The wavelengths of radio waves range from thousands of metres to 30 cm These correspond to frequencies as low as 3 Hz and as high as 1 gigahertz (10 9 Hz)

Radio waves have the longest wavelengths in the electromagnetic spectrum They range from the length of a football to larger than our planet Heinrich Hertz proved the existence of radio waves in the late 1880s He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna
- Radio Waves or Radio-Frequency Radiation - Science Notes and Projects
Radio Wave Definition Radio waves are electromagnetic waves with frequencies below 300 GHz (wavelengths longer than 1 mm) Like all EM radiation they travel at the speed of light (c = 3 00×10 8 m s) in a vacuum, but their long wavelengths give them unique propagation and interaction characteristics
