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.. There’s a whole lot of light out there!. The Electromagnetic Spectrum. The electro-magnetic spectrum is made up of visible and . nonvisible. light.. Electromagnetic waves are produced by stars and galaxies.. 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. 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.

Different types of light give us different information!. 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. .. Electromagnetic waves are a group of energy waves that are mostly invisible and can travel through empty space.. Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant..
