Waves

     There are two types of waves.A wave is a periodic disturbance in a solid, liquid or a gas as energy is transmitted through a medium. The two main waves are transverse wave and longitudinal. A transverse wave is a wave where the particles in a medium move perpendicularly to where the wave is going. A longitudinal a wave in where the particles of the medium vibrate parallel to where the wave goes.

       A medium is an environment where a phenomena occur some waves transfer energy through a medium. A crest is the highest point of the wave. A trough is the lowest part of the wave.
