  • The number of waves passing a point in a unit of time is called?
    frequency
  • Frequency is measured in ______.
    hertz
  • In the same medium, an increase in the frequency of the wave will cause a decrease in the ________________ of the wave.
    Wavelength
  • Which wave has the highest frequency?
    red
  • What does letter C represent on this wave?
    trough
  • What does letter A represent on this wave?
    crest
  • The energy of the wave can be indicated by the _______.
    Amplitude
  • What does letter D represent on this wave?
    wavelength
  • Wavelength is the distance between
    Two consecutive crests or troughs.
  • In a transverse wave, the particles of the medium move _________________ to the direction of the wave.
    At right angles (perpendicular)
  • What does letter B represent on this wave?
    amplitude
  • In a given medium, if the frequency increases, the wavelength ________.
    decreases
  • The maximum distance the molecules of a medium are displaced from their rest position is the
    Amplitude

  • The portions of a longitudinal wave that squeeze together are called:
    compressions
  • What type of wave is shown here?
    longitudinal/compression
  • The parts of a longitudinal wave that spread out are called _______.
    rarefaction
  • A _________________________ wave is a series of compressions and rarefactions.
    Longitudinal.
