3 TYPES OF MECHANICAL WAVES: 1) TRANSVERSE - a wave that causes the medium to vibrate at right angles (perpendicular) to the direction in which the wave travels. o o o Shaking a rope up and down Crest = highest point from rest position Trough = lowest point below rest position http://www.phy.hk/wiki/englishhtm/TwaveA.htm 2
2) LONGITUDINAL WAVE- a wave in which the vibration of the medium is PARALLEL to the direction the wave travels; sound waves are this type • Created by pushing and pulling in one direction • Compression = area where particles are spaced close together • Rarefaction = area where particles are spread out http://en.wikipedia.org/wiki/File:Longitudinalwave.ogg • http://www.acoustics.salford.ac.uk/feschools/waves/wavetypes.htm P waves ( primary waves ) caused by earthquakes 3
