properties of waves

• Frequency

  how many waves pass a point in a certain amount of time
• Wavelength

  the distance from crest to crest, OR trough to trough
• Speed

  the distance a wave travels in an amount of time

• High Frequency Wave

  
• Low Frequency Wave

  
• Transverse wave

  wave moves perpendicular to the direction of energy source (up and down)
• crest


  top of a wave
• trough

  bottom of a wave
• medium

  solid, liquid or gas
• light waves can travel through this

  transparent medium and empty space
• sound waves

  a longitudinal wave which travels through a medium
• light waves

  a transverse wave which doesn't need a medium
• frequency wavelength relationship

  inverse as one increases the other decreases
• sound waves can only travel through this

  medium
