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.. 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..

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.. FREQUENCIES . By John Bailey M0MTW. EXPLORING VLF and ELF FREQUENCIES. 1.What frequencies.
