General Physics 2/28/2011 A. Brahmia 1 1 ELECTROMAGNETIC WAVES Production of Electromagnetic Waves – Robert Maxwell concluded that changing magnetic field (B) will produce a changing electric field (E) and the changing electric field will produce a changing magnetic field. – The net result of the interaction of the changing (E) and (B) fields is the production of a wave which has both an electric and magnetic component and travels through empty space. – The wave is referred to as an electromagnetic wave (EM) . cB E 2 ELECTROMAGNETIC WAVES. .. The Electromagnetic Spectrum – Electromagnetic waves are produced by accelerating electric charges. Examples – Accelerating charges in atoms give off visible light . – Accelerating electric charge in an antenna produce radio waves .
