What is Electromagnetic Waves? Definition of. Echoes Echoes are sound waves bouncing off surfaces. Sound waves obey the same first rule of reflection. (Remember: the angle of incidence is the same as the angle of reflection.) The echo is usually quieter than the original noise as energy is lost as the wave travels along. /**/ You can work out how far away something is using echo-sounds., Applications of EM Waves. Wireless Communication. With infra-red waves, distances are short (such as a few meters for television remote control) while radio waves can reach as far as thousands or even millions of kilometers for deep-space radio communications..

Applications of EM Waves. Wireless Communication. With infra-red waves, distances are short (such as a few meters for television remote control) while radio waves can reach as far as thousands or even millions of kilometers for deep-space radio communications. In order to reach greater distances than line of sight, some radio waves can be made to travel towards the sky. (sky waves) The waves are then refracted by the ionosphere (layers of air stretching from 80 – 550 km above the Earth) and returned later to Earth. These wave signals are subsequently intercepted by receiving ground stations.

27.11.2007 · The energy in electromagnetic waves is sometimes called radiant energy. [edit] Particle model Because energy of an EM wave is quantized, in the particle model of EM radiation, a wave consists of discrete packets of energy, or quanta, called photons. The frequency of the wave is proportional to the magnitude of the particle's energy. Electromagnetic waves travel in a transverse form. Electromagnetic waves are not deflected by electric or magnetic field. These waves can be polarized. Electromagnetic Waves undergo interference and diffraction. The wavelength(λ) and frequency (v) of the EM waves can be related as: c= v.λ. where c = velocity of the wave.

Waves transfer energy in different forms, some are very useful, while others can be deadly. A Tsunamis or tidal wave is a very large water wave that has been produced by some kind of seismic phenomona. These waves can move at speeds of 500 km/h and have a period of 60 minutes. Just like the waves produced by a microwave oven, the radio waves used for communication consist of huge numbers of photons, all very nearly in phase. This gives them a much lower entropy than that of a similar number of photons with random phase.
