PPT-ELECTROMAGNETIC SPECTRUM

LIGHT ENERGY IS ELECTROMAGNETIC IN NATURE IT CAUSES A SENSATION OF VISION ELECTROMAGNETIC RADIATIONS WHICH CAN EXCITE OUR RETINA HAS WAVELENGTH BETWEEN 8000 ANGSTROM TO 4000 ANGSTROM ANGSTROM IS THE UNIT TO MEASURE WAVELENGTH. Section . 1- What . are electromagnetic waves?. WHAT DO CORDLESS PHONES AND MICROWAVE OVENS HAVE IN COMMON?. Each emits electromagnetic waves.. Remember…. A . wave. . is a repeating disturbance or movement that transfers energy through matter or space.. Major Jay . Yniguez. (E. -knee-guess. ). Lead EW Engineer. Future Capabilities Division. Joint Electronic Warfare Center. United States Strategic Command. Lackland. Air Force Base, Texas. . IEEE . 8. th. 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. . Almost all of our information on the heavens is derived from the light we see. We have returned samples from the Moon and a comet . Also obtained meteor samples. We have landed (with unmanned probes) on only a handful of planets and moons. 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. Mrs. Molloy. 6. th. Grade Science. Electromagnetic Waves…. Do not need matter to transfer energy.. Made by vibrating electric charges.. Travel by transferring energy between electric and magnetic fields.. 1. The Electromagnetic Spectrum. Wavelength/frequency/energy. MAP TAP 2003-2004. The Electromagnetic Spectrum. 2. Teacher Page. Content: Physical Science—The Electromagnetic Spectrum. Grade Level: High School. 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. College Physics Chapter 24 ELECTROMAGNETIC WAVES PowerPoint Image Slideshow Figure 24.1 Human eyes detect these orange “sea goldie ” fish swimming over a coral reef in the blue waters of the Gulf of . 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. . 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..
