All waves carry … ENERGY!!!. Electromagnetic Waves (light) . Light waves are . transverse. waves. Electromagnetic. Radiation. Energy emitted from the . 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.. 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. . Review of the Quasi-static Approximation.

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. . Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. Light, microwave, x-ray, TV, and cell phone transmission are all kinds of . electromagnetic waves. ..

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..
