The electromagnetic wave theory states that any acceleration of an electric charge or change in the magnetic field produces radiation. - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. w wang 2 The incident beam is characterized by its wavelength λi, its frequency νi and its velocity c0 and refracted beam is characterized by its wavelength λr, its frequency νr and its velocity c, the simple dispersion relation for vacuum. Lecture 13 Notes, Electromagnetic Theory I Dr. Christopher S. Baird University of Massachusetts Lowell 1. Do you have PowerPoint slides to share? An electromagnetic wave exists when the changing magnetic field causes a changing electric field, which then causes another changing magnetic field, and so on forever.
