    Cards (132)

    • What do waves transfer without transferring matter?
      Energy and information
    • How is a wave defined?
      A wave is a disturbance that travels through a medium.
    • What happens when a pebble is dropped into water?
      Ripples spread outward, transporting energy.
    • What is the role of medium particles in wave energy transfer?
      They vibrate back and forth around their equilibrium position.
    • How do particles transmit energy in a wave?
      Each particle transmits energy to its neighbor.
    • What does the electromagnetic spectrum illustrate?
      Different waves transfer energy without moving matter.
    • How do waves transfer information?
      By carrying a disturbance through a medium.
    • Which wave type transmits sound without moving air molecules forward?
      Sound waves
    • What type of waves travel through space carrying energy from the sun?
      Light waves
    • How do seismic waves transfer energy during earthquakes?
      Through vibrations in Earth's layers without moving rock.
    • What do water waves do when they propagate energy?
      They cause water particles to oscillate without moving forward.
    • What are examples of waves that transfer energy without matter?
      • Sound: Vibrations in air transmit sounds.
      • Light: Electromagnetic waves travel through space.
      • Seismic waves: Travel through Earth's layers.
      • Water waves: Ripples propagate energy outward.
    • In wave motion, what do particles do around their equilibrium position?
      They oscillate in place.
    • What happens to rock particles during seismic waves?
      They vibrate while the wavefront travels horizontally.
    • What type of motion describes the oscillation of links in a hanging chain?
      Wave motion
    • What type of motion describes the movement of a seismic wavefront?
      Wave motion
    • What type of motion describes the movement of the wavefront during seismic waves?
      Wave motion
    • How do rock particles behave during seismic waves?
      They vibrate up and down around their position
    • What is the difference between wave motion and particle motion?
      Wave motion transfers energy without permanent movement
    • How can you explain wave motion to a child?
      • Like a slinky moving in waves
      • Coils wiggle but don't move far
      • Energy travels through the slinky
    • How does the motion of spectators in a stadium wave differ from wave propagation?
      Spectators oscillate, while the wave propagates
    • What happens to rock particles during an earthquake?
      They oscillate vertically around their positions
    • What is the relationship between rock particle motion and seismic wave motion during an earthquake?
      Rocks exhibit particle oscillation, waves exhibit wave motion
    • How do you describe the motion of rock particles and seismic waves during an earthquake?
      Rock particles oscillate, seismic waves travel horizontally
    • What is the formula that relates frequency and period of a wave?
      f=f =1T \frac{1}{T}
    • If a wave has a period of 0.5 seconds, what is its frequency?
      2 Hz
    • What is the frequency of a water wave that completes one oscillation every 0.2 seconds?
      5 Hz
    • What type of motion do water molecules exhibit in water waves?
      Up and down motion
    • What happens to air molecules when a sound wave travels through air?
      They vibrate around their original positions
    • What is the primary motion of water molecules in deep water waves?
      Circular motion
    • How do air molecules behave during the compression phase of a sound wave?

      They move towards each other along the wave direction
    • What is created when you drop a stone into a pond?
      Water waves that spread outward
    • What happens to air molecules when sound waves propagate?
      They vibrate but do not travel
    • What do water waves demonstrate about energy transfer?
      Energy moves without matter transport
    • What type of motion do water molecules exhibit in shallow water?
      Elliptical motion due to friction
    • How do seismic waves differ from water and sound waves?
      Seismic waves show different particle motions
    • What type of motion do P waves cause in particles?
      Back-and-forth along wave direction
    • What is the primary characteristic of Rayleigh waves?
      Elliptical motion of particles
    • How do waves transfer energy compared to matter movement?

      Waves transfer energy, matter vibrates locally
    • What is the definition of frequency in relation to waves?
      The number of oscillations per second.
