Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.]]> 2016-12-19 18:38:13 UTC https://padlet.com/12238535/z44ot6mxnl7d/wish/144368457 TRANSVERSE WAVESa wave vibrating at right angles to the direction of its propagation. 12238535 https://padlet.com/12238535/z44ot6mxnl7d/wish/144368690 2016-12-19 18:39:22 UTC https://padlet.com/12238535/z44ot6mxnl7d/wish/144368690 LONGITUDINAL WAVESa wave vibrating in the direction of propagation. 12238535 https://padlet.com/12238535/z44ot6mxnl7d/wish/144368961 2016-12-19 18:40:46 UTC https://padlet.com/12238535/z44ot6mxnl7d/wish/144368961 WAVELENGTHthe distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave 12238535 https://padlet.com/12238535/z44ot6mxnl7d/wish/144369341 2016-12-19 18:42:35 UTC https://padlet.com/12238535/z44ot6mxnl7d/wish/144369341 FREQUENCY the rate at which something occurs or is repeated over a particular period of time or in a given sample. 12238535 https://padlet.com/12238535/z44ot6mxnl7d/wish/144369481 2016-12-19 18:43:19 UTC https://padlet.com/12238535/z44ot6mxnl7d/wish/144369481 RADIO WAVES 12238535 https://padlet.com/12238535/z44ot6mxnl7d/wish/144369572 Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long. Radio waves are often used to transmit data and have been used for all sorts of applications including radio, satellites, radar, and computer network

This is the range of wavelengths from 390 to 700 nm which corresponds to the frequencies 430-790 THz.

It is ultraviolet rays from the Sun that cause sunburns.

Gamma rays are the shortest waves in the spectrum and, as a result, have the most energy. Gamma rays are sometimes used in treating cancer and in taking detailed images for diagnostic medicine. Gamma rays are produced in high energy nuclear explosions and supernovas.
