This will therefore explain how light travels through an optical fibre and show how such fibres are used in medicinal equipment either to transmit light or to bring back images from within a patient.

Investigatory Projects in Physics | Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were

to organize network traffic‚ along with the network’s size‚ its topology and its organizational intent. The communication media used to connect devices to form a computer network include electrical cable (HomePNA‚ power line communication‚ G.hn)‚optical fiber (fiber-optic communication)‚ and radio waves (wireless networking). In the OSI model‚ these are defined at layers 1 and 2 — the physical layer and the data link layer. A widely-adopted family of communication media used in local area network

The Telescope (Reflecting) Introduction: The true beauty of the universe cannot be seen by just the naked eye‚ the telescope is controversially the most important optical instrument in history. Telescopes are widely used around the world and come in different shapes‚ sizes and go by a variety of different names. They can be used to detect noise and sound and even be used to study the stars and supernovas but are more commonly used to gain another perspective into space‚ watching planets such

Fiber optic cable – a cable made of optical fibers that can transmit large amounts of information at the speed of light. 5. Dark fiber – Dark fiber or unlit fiber is unused optical fibers available for use in fiber optic communications. 6. Coaxial cable – a transmission medium used for high frequency signals. 7. Plenum – Plenum cable is cable that is
