  • How are sound and light waves different with respect to a medium?
    Sound requires a medium, light does not.
  • Define crest
    the top curve of a transverse wave
  • Which type of wave is this?
    transverse
  • Which type of wave is this?
    longitudinal
  • Which property of a wave do we use to represent the pitch?
    frequency
  • define rarefaction
    in a longitudinal wave, where the particles are spread apart
  • Waves are caused by ______
    vibrations
  • Which wave moves perpendicular to to the medium (if there is one)
    transverse
  • What is the relationship between frequency and wavelengh?
    they are inversely related
  • Define trough
    the bottom curve of the wave
  • higher frequency waves have more ________
    energy
  • As the wavelength increases, the energy ___________
    decreases
  • define wavelength
    distance between 2 crests or troughs
  • The amplitude measures the ________ of a wave
    intensity
  • A wave carries ___________
    energy
  • define compression
    in a longitudinal wave where the particles are bunched together
  • sound travels slowest in ______
