Types of waves

Cards (35)

  • What are waves used for in energy transfer?
    Waves transfer energy between stores.
  • What types of waves transfer energy?
    Both mechanical and electromagnetic waves transfer energy.
  • Do waves transfer matter?
    No, waves transfer energy but not matter.
  • What is a wave described as?
    A wave is described as oscillations or vibrations about a rest position.
  • How do sound waves affect air particles?
    Sound waves cause air particles to vibrate back and forth.
  • What do ripples in water cause particles to do?
    Ripples cause water particles to vibrate up and down.
  • What distinguishes longitudinal waves from transverse waves?
    Longitudinal waves have vibrations parallel to wave travel, while transverse waves have vibrations at right angles.
  • What is a longitudinal wave?
    A longitudinal wave is a wave that moves in the same direction as the particles are vibrating.
  • What is a transverse wave?
    A transverse wave moves at right angles to the direction of particle vibrations.
  • What do mechanical waves require to travel?
    Mechanical waves require a medium to travel through.
  • What happens to the medium after a wave passes through it?
    The medium returns to its rest position after the wave passes.
  • What are electromagnetic waves responsible for?
    Electromagnetic waves cause oscillations in electrical and magnetic fields.
  • What type of waves are all electromagnetic waves?
    All electromagnetic waves are transverse waves.
  • What is matter defined as?
    Matter includes sub-atomic particles, atoms, and molecules.
  • What is the rest position of a wave?
    The rest position is the undisturbed position of particles when they are not vibrating.
  • What does displacement refer to in a wave?
    Displacement is the distance a point in the medium has moved from its rest position.
  • What is the peak of a wave?
    The peak is the highest point above the rest position.
  • What is the trough of a wave?
    The trough is the lowest point below the rest position.
  • What does amplitude refer to in a wave?
    Amplitude is the maximum displacement of a point of a wave from its rest position.
  • How is wavelength measured?
    Wavelength is usually measured from peak to peak or trough to trough.
  • What is the time period of a wave?
    The time period is the time taken for a full cycle of the wave.
  • What is frequency in the context of waves?
    Frequency is the number of waves passing a point each second.
  • What are the key parts of a wave and their definitions?
    • Rest position: Undisturbed position of particles.
    • Displacement: Distance moved from rest position.
    • Peak: Highest point above rest position.
    • Trough: Lowest point below rest position.
    • Amplitude: Maximum displacement from rest position.
    • Wavelength: Distance covered by a full cycle.
    • Time period: Time taken for a full cycle.
    • Frequency: Number of waves passing a point each second.
  • How do mechanical waves differ from electromagnetic waves?
    Mechanical waves require a medium, while electromagnetic waves do not.
  • What happens to the medium after a mechanical wave passes through?
    The medium returns to its rest position after the wave passes.
  • What is the relationship between waves and energy transfer?
    Waves are a means of transferring energy between stores.
  • What is the significance of the medium in mechanical waves?
    The medium is essential for the propagation of mechanical waves.
  • How do the oscillations in longitudinal waves differ from those in transverse waves?
    In longitudinal waves, oscillations are parallel to wave travel; in transverse waves, they are perpendicular.
  • What is the role of amplitude in a wave?
    Amplitude indicates the maximum displacement from the rest position, affecting wave energy.
  • How is frequency calculated?
    Frequency is calculated as the number of waves passing a point per second.
  • What is the importance of measuring wave speed?
    Measuring wave speed helps understand how quickly energy is transferred through a medium.
  • How do the properties of waves relate to their energy transfer capabilities?
    The properties of waves, such as amplitude and frequency, influence their energy transfer efficiency.
  • What is the significance of the wave period in wave behavior?
    The wave period indicates how long it takes for one complete cycle of the wave to occur.
  • What is the definition of wavelength?
    Wavelength is the distance covered by a full cycle of the wave.
  • How does the concept of waves apply to sound and light?
    Both sound and light are transmitted as waves, transferring energy through different mediums.
