Electromagnetic vibrations, waves, and radiation ( edition) | Open Library

Accelerating charges produce changing electric and magnetic fields. Changing electric fields produce magnetic fields and changing magnetic fields produce electric fields. This interplay between induced electric and magnetic fields leads to propagating electromagnetic waves. Electromagnetic waves can propagate through free space. Assume a charge q located near the origin is accelerating. It therefore produces electromagnetic radiation.

Electromagnetic waves and the electromagnetic spectrum - Physics - Khan Academy

By George Bekefi and Alan H. The book describes the features that vibrations and waves of all sorts have in common and includes examples of mechanical, acoustical, and optical manifestations of these phenomena that unite various parts of physics. The main emphasis, however, is on the oscillatory aspects of the electromagnetic field—that is, on the vibrations, waves, radiation, and the interaction of electromagnetic waves with matter.

Tour of the Electromagnetic Spectrum

Radio waves are EM Electromagnetic waves that have wavelengths between 1 millimeter and kilometers or GHz and 3 kHz in frequency. Radio waves are a type of electromagnetic EM radiation with wavelengths in the electromagnetic spectrum longer than infrared light. They have have frequencies from GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to kilometers. Like all other electromagnetic waves, radio waves travel at the speed of light. Naturally occurring radio waves are made by lightning or by astronomical objects. Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, communications satellites, computer networks and innumerable other applications.
