PHYS 117 Chapter Notes - Chapter 21: Plane Wave, Magnetic Monopole, Transverse Wave
Document Summary
Physics 117 chapter 21 alternating-current circuits and electromagnetic waves. Free magnetic charges (magnetic monopoles) don"t exist in nature. Electromagnetic waves: waves sent out by the oscillating charges are fluctuating electrical and magnetic fields. 21. 10 production of electromagnetic waves by an antenna. Whenever a charged particle accelerates, it radiates energy. A plane electromagnetic wave is a wave travelling from a very distant source. The speed of an electromagnetic wave is related to the permeability and permittivity of the medium through which it travels. Electromagnetic waves travel at the speed of light. Electromagnetic waves carry both energy and momentum, which can be delivered to a surface. All electromagnetic waves travel in a vacuum with the speed of light.
