Wave Properties

Wave Properties

1. Longitudinal

   • sound
   • ultrasound
   • shock (P-earthquake)
   • sound travels as waves made up of vibrating air particles
   • the particles vibrate back and forth, so he direction of their movement is parallel to the direction of the wave

2. Transverse

   • examples
     • wave on a string
     • water
     • mexican
     • gamma
     • x-ray
     • ultra violet
     • light (visible)
     • infra-red
     • micro
     • radio
     • shock (S-earthquake
   • in transverse waves, the particles move up and down, so the direction of their movement is at right angles to the direction of the wave

3. coherent wave

   • two waves that have the same frequency, a similar amplitude and are from a similar source

4. phase difference

   • a measurement the tells us the difference between how two waves move
