uses electrical signals to transmit data. It uses light. In fiber optic cable light only moves in one direction for two way communication to take place a second connection must be made between the two devices. Microwave Electromagnetic radiation beyond the frequency range of radio and television can be used to transport information. Microwave transmission is usually point-to-point using directional antennae with a clear path between transmitter and receiver.

“Nuclear Technology is the leading international publication reporting on new information in all areas of the practical application of nuclear science.” (American Nuclear Society) Today‚ nuclear technology is used for a variety of reasons that include weapons‚ medicine‚ food and agriculture‚ smoke detectors‚ and environmental protection. However‚ many people see nuclear technology as a destruction that could eventually kill us all. In addition‚ people believe that if scientists keep developing and

ground state‚ several distinct energy emissions occur. Electrons may become excited when a sample of matter is heated or subjected to an electrical current. The energy that electrons emit when returning to the ground state is electromagnetic radiation‚ or EMR. Sometimes the EMR can be seen as visible light. In 1900‚ Max Planck studied visible emissions from hot glowing solids. He proposed that light was emitted in packets of energy called quanta and that the energy of each packet was proportional

Earth. He soon discovered many more binary and multiple stars than expected‚ and compiled them with careful measurements of their relative positions. Ritter discovered ultraviolet‚ he believed and hypothesized that there must also be invisible radiation beyond the violet end of the spectrum He measured the speed at which different colours of light were broken down‚ As a result‚ Ritter confirmed the common belief that violet light was more effective than red‚ this is now knows as ultraviolet.Some

eyelashes and body hair may also shed. Common causes of this condition are intake of cytostatic drugs usually recommended for cancer patients. In case of chemotherapy‚ this hair loss process happens shockingly fast. This might also occur due to radiation therapy‚ autoimmune disease‚ ingestion of toxic drugs for instance rat poison‚ or an infection like fungal hair infection.
