Wave. —a repeating movement or disturbance that transfers energy through matter or space. . All waves carry energy without transporting matter from place to place. . RADAR. By Tony Kim and Ross Chu. Block D. Physics. RADAR which stands for . RAdio. Detection And Ranging was developed by Britain in the late 1930’s, during WW2. Before the war, Radars were used to detect objects through the usage of radio waves. 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. Alex Hills. Chapter 27. Summary. Communication engineer Alex Hills explains how the satellite communications systems he designed for rural Alaskans helped him develop Wi-Fi system. Because of tough terrain, laying telephone wire was not feasible, and shortwave radio signals often met interference from the Northern Lights. Alex helped devise a communications system using satellite technologies that allowed rural Alaskans to communicate across the tundra. Eventually, Hills was instrumental in linking the state’s university campuses together via satellite. The wireless network inspired Hills to develop the first Wi-Fi at Carnegie Mellon University in the 90’s.. 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. . 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!. Wave. Repeating disturbance or movement. Carries energy through matter and space. Vibrations. Anything that moves in a rhythmic patter. Up and down. Back and forth. What is a Wave. All waves are produced when something vibrates. 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.. 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1. Agenda. Binder Check/Homework review.
