2 A wave is a disturbance that carries energy through matter or space

4 Water waves are a type of surface wave where two different media meet (example air and water) http://imagers.gsfc.nasa.gov/ems/waves.html http://imagers.gsfc.nasa.gov/ems/waves.html

5 In surface waves the particles move in a circular motion http://imagers.gsfc.nasa.gov/ems/waves.html http://imagers.gsfc.nasa.gov/ems/waves.html

7 http://library.thinkquest.org/C005705/English/Waves/wavety pes.htm Mechanical waves – need a medium to go through Electromagnetic waves – don’t need anything to travel through.

8 http://library.thinkquest.org/C005705/English/Waves/wavety pes.htm Almost all waves are mechanical waves and require a medium to travel.

9 Simple harmonic motion http://library.thinkquest.org/C005705/English/Waves/spring.htm

10 http://library.thinkquest.org/C005705/English/Waves/wavety pes.htm A medium is matter through which a wave travels such as air or water.

11 http://library.thinkquest.org/C005705/English/Waves/wavety pes.htm http://www.phy.ntnu.edu.tw/java/waveType/waveType.html Wave shapes are either longitudinal or transverse

19 Electromagnetic Waves Electromagnetic Waves do not need a medium to travel through. They can go through space.

20 Electromagnetic waves are transverse waves with a variety of wavelengths and frequencies.
