PPT-WAVES AND THE ELECTROMAGNETIC SPECTRUM

Waves Wave A repeating movement or disturbance that transfers energy through matter or space All waves carry energy without transporting matter from place to place Molecules pass energy along to neighbor molecules who then pass energy to neighbor.

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.. Lesson 9. Parts of a Wave. (1 second). Which wave has the most energy?. How do you know? (evidence). Step. 4. Step. 5. What is the relationship between energy and wavelength?. Red = 780 nm. Wavelengths of Color. Light:. Temperature, Scattering & Absorption. Essential Standards. 6.P.. 3 Understand . characteristics . of energy . transfer and interactions of matter and energy.. Clarifying Objectives. 6.P .. 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. . Review of the Quasi-static Approximation. Electric and Magnetic Components of Waves. The Wave Equation (in 1-D). Uniform Plane Waves. Phase Velocity and Intrinsic Impedance. Wave-vector and Wave-frequency. What is light?. Light is a wave: . Explains much of the everyday behavior of light. Light is a particle: . Explains why heated objects emit only certain frequencies of light at a given temperature. Light as Waves. Not all waves are the same. (Please draw the picture and write your answers in complete sentences.). 1. How are the waves different from each other?. 2. . Which wave has the highest frequency? Which wave has the lowest? How do you know?. Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. March 25. June 18. September 26. December 19. http://video.pbs.org/video/2219781967/. Electromagnetic Waves. Believe it or not, you are being . “. showered. ”. all the time, not by rain but by waves. . 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1. Agenda. Binder Check/Homework review. Electromagnetic Wave overview. Wave Overview. Spectrum Overview. Particle and Wave Properties. Speed equations. 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..
