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 . 1.Electromagnetic Waves2.Properties of Electromagnetic Waves3.Hertz Experiment4.Electromagnetic Spectrum -Wavelength and Frequency Range-Sources and Uses Electromagnetic Waves: For a region where ther Leading Forward in Times of . Change. 1. 2. Goals. Accountability for the sake of STAAR. Review . the . STAAR design and standards. Connect STAAR. to the curriculum. to the data from TAKS. to units in the curriculum. 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. . Light:. Temperature, Scattering & Absorption.

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. . 4.f. Describe the hierarchical structure (stars, cluster, galaxies, galactic clusters) of the universe & examine the expanding universe to include its age & history & the modern techniques (e.g. radio, infrared, ultraviolet & x-ray astronomy) used to measure objects & distances in the universe. (DOK 2). Chapter 9 . Trapped in a Newtonian Universe. Though Newton’s Apple and Calculus are helpful, his theories are only as good as the next round of evidence.. Now we have electromagnetic fields and energy without tiny solid particles.. 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.

The next slides show images of the SAME region of sky, but using different types of light. The view in VISIBLE LIGHT. INFRARED. RADIO WAVES. RADIO WAVES. GAMMA RAYS. Different types of light give us different information!. . 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..
