RADIO WAVES HOW DO RADIO WAVES HELP ASTRONOMERS Astronomers learn about a stars composition structure and motion MICROWAVES HOW DO ASTRONOMERS USE MICROWAVES ASTRONOMERS PICK UP THE COSMIC MICROWAVE BACKGROUND THAT WAS LEFT OVER FROM THE BIG BANG. 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. . The stars and other objects in space are very far from Earth. Only a few solar system objects are close enough to be explored with probes. . Astronomers rely on electromagnetic waves to gain information about the universe.. 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.. 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. 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. . 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. 6. th. grade . Mrs. Messina. DO NOW. : 2/23/16. T. hink about the term “. electromagnetic. ”. . List as many things . that you can think of that are considered electromagnetic.. Electromagnetic energy. 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. 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. 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 .
