    Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz to as low as 30 hertz. At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is 10,000 km.

    Electromagnetic Radiation is a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.

    A Radio-wave is an electro-magnetic wave. 

    The wavelength is in the region of 20 metres.????

    White light is also an electro-magnetic wave, with a waelength in nanometres. 

    Cosmic< X-rays<UV< White light< Infra-red< microwaves< Radiowave are all electro-magnetic waves with increasing wavelength.  They all pass through a vacuum.
