1. Wavelengths

   • Longtitudal
     • wave goes up and down
       • Particles go side to side
   • Transverse
     • wave goes side to side
       • Particles go up and down
   • Amplitude
     • Maximum displacement either above or below the rest position of a wave. Distance from the middle to the top or bottom of a wave
   • Peak
     • Maximum point above the rest position of a wave. Top of the wave, highest point. Also called a crest.
   • Trough
     • Maximum point below the rest position of a wave. Bottom of the wave, lowest point
   • Frequency
     • The number of waves per second, measured in Hertz (Hz). Low frequency = slow, small waves. High frequency = quick, tall waves.
   • Wavelength
     • Distance between two peaks or troughs of a wave
