PPT-P O L A R I Z A T I O N EM Waves

Light is an electromagnetic wave EM waves are transverse Thus the electrical field can vibrate in any direction perpendicular to the direction of propagation Most light sources candles incandescent light bulbs etc emit light that is unpolarized the electric field has all possible directions of vibrations.

Wave. —a repeating movement or disturbance that transfers energy through matter or space. . All waves carry energy without transporting matter from place to place. . Physics 4. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. Maxwell’s Equations. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. Maxwell’s equations summarize the relationships between electric and magnetic fields. A major consequence of these equations is that an accelerating charge will produce electromagnetic radiation.. Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source of the wave.. If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease. Prairie High School Physics. © 2014 Pearson Education, Inc.. Chapter Contents.

Electromagnetic Radiation. Electromagnetic waves perpendicular waves combing the electric and magnetic fields. . Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . Waves transfer energy!. A wave does not carry matter . It only moves matter as it travels through it.. Waves. Compression (longitudinal) waves . are waves in which the particles of the medium move in a direction . A wave is any disturbance that transmits energy through matter or empty space.. Energy can be carried away from it’s source by a wave. As a wave travels, it does work on everything in it’s path. 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1. Agenda. Binder Check/Homework review. Mechanical Wave overview.

Wind main disturbing force. Boundary between and within fluids with different densities. The Scottish physicist James Clerk Maxwell (1831–1879) was the first person to truly understand the fundamental nature of light. . He proved in 1865 that an electromagnetic disturbance should propagate in free space with a speed equal to that of light..
