    2 mm
  • Name 3 properties of a wave.
    wavelength, amplitude, frequency
  • How are sound waves different than light waves?
    Sound waves require a medium, but light waves do not.
  • Which type of wave has an up and down motion?
    transverse wave
  • Name 3 ways to measure wavelength
    origin to origin, crest to crest, trough to trough
  • What kind of wave does not require a medium and could travel through empty space?
    electromagnetic wave
  • Which type of wave has a side-to-side motion?
    longitudinal wave
  • What is the wavelength of this wave?
    2
  • Which is faster, a light or sound wave?
    light
  • Define amplitude
    The height of a wave from resting point to crest or trough.
  • As wavelength increases, what happens to the energy of a wave?
    The energy will decrease.
  • Define "trough"
    The lowest point of a wave
  • As frequency increases, what happens to the energy of a wave?
    The energy increases also.
  • Define wavelength
    The length between corresponding parts of a wave
  • What moves through a wave?
    energy
  • What kind of wave requires a medium?
    mechanical wave
  • Define "crest"
    The highest point of a wave
  • What is the relationship between frequency and wavelength?
    Frequency and wavelength have an inverse relationship.
  • Define frequency
    The number of waves that paces a given point in 1 second
  • What is the frequency of this wave?
    3 Hertz
  • What unit do we use to measure frequency? Hint: Hz
    Hertz
