Grade Physical Science . Question: . What type of wave is a sound wave? . Waves. 3/10/15. Wave. —a repeating movement or disturbance that transfers energy through matter or space. . All waves carry energy without transporting matter from place to place. . Outline. 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. There’s a whole lot of light out there!. The Electromagnetic Spectrum. The electro-magnetic spectrum is made up of visible and . nonvisible. light.. Electromagnetic waves are produced by stars and galaxies.. 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. Sound. Sound waves are compressional waves.. Two regions: compressions and rarefactions. Sound travels faster in liquids and solids than in gases.. Why? The molecules in liquids and solids are closer together.. Electromagnetic Waves. Electromagnetic (EM) waves . are waves caused by oscillations occurring simultaneously in electric and magnetic fields. A . 2D. transverse. wave. They DO NOT require any medium in order to propagate. . What do X­rays, light, microwaves, radio waves, and infrared have in common? . . EM Radiation. Radiation can be described as the movement of energy through space. . There are many different sources of radiation that vary by intensity. . Electromagnetic Waves. Electromagnetic (EM) waves . are waves caused by oscillations occurring simultaneously in electric and magnetic fields. A . 2D. transverse. wave. They DO NOT require any medium in order to propagate. they are: Geometrical optics - this area of optics operates on the primary assumption that light travels in a straight line. Although this is an abstraction of reality, it nevertheless permits rathe Light, microwave, x-ray, TV, and cell phone transmission are all kinds of . electromagnetic waves. .. Electromagnetic waves are a group of energy waves that are mostly invisible and can travel through empty space.. Waves. What is a wave?. A wave is a disturbance that travels from one location to another location. The traveling disturbance in a wave is carrying energy (NOT matter). Waves that require a medium to travel through are . 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..
