PPT-Electromagnetic Waves! The EM and Visible Spectra

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. 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. Essential Standards. 6.P.. 3 Understand . characteristics . of energy . transfer and interactions of matter and energy.. Clarifying Objectives. 6.P .. Physics 4. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. Maxwell’s Equations. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. 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.. . WAVES. MAXWELL’S EQUATIONS. ELECTROMAGNETIC WAVES. INTRODUCTION. JAMES CLARK MAXWELL OF SCOTLAND GAVE A SET OF FORMULAE FOR ELECTRIC CHARGE, CURRENT AND THEIR ELECTRIC FIELD AS WELL AS MAGNETIC FIELD.. 14-11. Ultraviolet and visible light give rise to electronic excitations.. Spectroscopy of organic molecules is possible because the absorption of radiation is restricted to quanta having energies corresponding to specific molecular excitations:. the Electromagnetic Spectrum.

T. hink about the term “. electromagnetic. ”. . List as many things . that you can think of that are considered electromagnetic.. Electromagnetic energy. 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?. Gravitational Wave Bonus). 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.. 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..
