  • What do waves transfer from one place to another?
    Energy
  • How does light from the Sun travel to Earth?
    Through space and the atmosphere
  • How does sound travel from a loudspeaker?
    By transferring energy to absorbing objects
  • What are waves called that move through a substance with particles vibrating at right angles?
    Transverse waves
  • How do particles move in longitudinal waves?
    Backwards and forwards in the same direction
  • How can transverse waves be created?
    By shaking a rope up and down
  • In a transverse wave, how is the oscillation oriented?
    At right angles to energy transfer
  • What direction do particles move in a transverse wave?
    Up and down
  • What happens to particles in a transverse wave?
    They are not transported along the wave
  • What types of waves are sound waves classified as?
    Longitudinal waves
  • How can longitudinal waves be created?
    By pushing a slinky forwards and backwards
  • In a longitudinal wave, how is the vibration oriented?
    Parallel to the direction of energy transfer
  • What is a compression in a longitudinal wave?
    A region of high pressure

    A region of low pressure
  • How is amplitude defined in longitudinal waves?
    Maximum distance from rest position
  • How is wavelength measured in longitudinal waves?
    From center of one compression to next
  • What does frequency measure in waves?
    Number of vibrations in one second
  • What unit is frequency measured in?
    Hertz (Hz)
  • What is the time period of a wave?
    Time for one complete cycle
  • What are the important terms used to describe waves?
    • Peak

    • Amplitude
    • Wavelength
    • Frequency
    • Time period
  • How can displacement-distance graphs be used?
    To compare amplitude and wavelength of waves
  • What does a displacement-time graph demonstrate?

    Displacement of one point on the wave over time
  • How can displacement-time graphs be used?
    To compare the number of waves in a time period
  • What does a shorter time period in a wave indicate?
    Higher frequency
