What are electromagnetic waves? Electromagnetic waves When the electric current changes in a very high frequency in an electric circuit, it starts circulating in the form of energy waves from the circuit. These waves are electromagnetic waves. In these waves the electric field E and magnetic field B are mutually perpendicular and the transmission of the wave Are also perpendicular to the direction of the medium and are not required for their transmission. Electromagnetic waves are a form of energy that is all around us and takes many forms, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. These waves are produced by the acceleration or oscillation of electric charges. Electromagnetic waves can travel through vacuum as well as through various mediums like air, water, and solids. Here are some key characteristics and properties of electromagnetic waves: 1. Electric and Magnetic Fields: Electromagnetic waves consist of per...
