Waves

Waves

1. what are waves- energy transfer

   • Transverse move perpendicular to direction of travel
     • high point=crest
     • low point= trough
   • longitudinal travels parallel to direction of wave
     • compression
     • rarefaction
   • caused by vibration
   • all waves except light require a medium

2. Properties

   • amplitude
     • maximum distance the particles of the medium carry the wave from the rest position
   • wavelength
   • frequency
   • speed
     • speed is the wavelength times the frequency
