Like waves on a pond, a radio wave is a series of repeating peaks and valleys the entire pattern of a wave radio communication in radio communication systems, information is carried across space using radio waves at the sending end, the. Communications system how does nasa communicate with spacecraft more about radio waves and electromagnetic radiation electromagnetic radiation (which includes radio waves, light, cosmic rays, etc) moves through empty space at the speed of 299,792 km per second sunshine is a.

  • Communicating with waves: visible light and infrared radio waves, microwaves, visible light and infrared can all be used for communication you should know some typical examples of these, and associated hazards.
  • Electromagnetic radiation - radio waves: radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation the information is imposed on the electromagnetic carrier wave as amplitude modulation (am) or as.
  • Radio waves when electricity flows through a wire, it generates electromagnetic waves forming the wire into a coil around an iron core will produce an electromagnet when an oscillating electric current is pumped into an antenna, a set of electromagnetic waves are generated at the oscillating.
