WAVE Disturbance that transfers energy from one place to another. Medium: __________________________________ __________________________________________ Substance through which waves can travel. Example: solid, liquid, gas or space
Transverse Waves Move up and down at right angles (Ex. Light, ocean wave) Transverse waves can travel in _________________ a medium or in space
Longitudinal Waves Move back and forth in the direction of wave (straight) Ex. sound, compressing a spring
Longitudinal Waves cont. Longitudinal waves do not _________________ Longitudinal waves need a ________________ Compression= ___________________________ Rarefaction= ____________________________ *particles of a medium DO NOT move in the same direction as a wave, only the energy moves. travel in space. medium. close together particles. far apart particles.
