1. Types of Waves and Their Properties

2. Transverse Waves Particles vibrate at right angles to the direction the wave is traveling Transverse Waves Particles vibrate at right angles to the direction the wave is traveling The wave (the disturbance) travels this direction But the particles travel back & forth in this direction

3. Transverse Waves Particles vibrate at right angles to the direction the wave is traveling Transverse Waves Particles vibrate at right angles to the direction the wave is traveling The wave (the disturbance) travels this direction But the particles travel back & forth in this direction

4. Transverse Wave Example: Seismic Wave – the “S” [secondary] wave

5. Transverse Wave Example:

6. Transverse Wave Example: Light – an electromagnetic wave Made of vibrating electrical fields and magnetic fields

7. Longitudinal Particles vibrate in the same direction as the direction the wave is traveling Longitudinal Particles vibrate in the same direction as the direction the wave is traveling The wave (the disturbance) travels this direction And the particles move back and forth in this direction

8. Longitudinal Particles vibrate in the same direction as the direction the wave is traveling Longitudinal Particles vibrate in the same direction as the direction the wave is traveling The wave (the disturbance) travels this direction And the particles move back and forth in this direction

9. Longitudinal Wave example: Seismic “P” (“primary”)-wave

12. Surface waves The wave (the disturbance) travels this direction... And the particles cycle around in this direction
