mechanical waves

• What do waves transfer from one place to another?

  Energy
• What is the difference between transverse and longitudinal waves?

  Transverse waves oscillate perpendicular; longitudinal waves oscillate parallel
• What happens when a light object is dropped into still water?

  It produces ripples that spread out
• What occurs when you speak in terms of sound waves?

  Your voice box vibrates, creating sound waves
• What do mechanical waves require to travel?

  A substance (medium)
• What happens to particles in a substance when waves travel through it?

  Particles oscillate and pass energy to neighbors
• How do longitudinal waves affect particles in a substance?

  They cause particles to compress and rarefy
• What changes when waves travel from one medium to another?

  Speed and wavelength may change, frequency stays the same
• What is amplitude in relation to waves?

  Maximum displacement from undisturbed position
• How is frequency measured?

  In Hertz (Hz)
• What does the period of a wave represent?

  Time taken for one complete wave to pass
• What is wavelength?

  Distance from one point on a wave to the next equivalent point
• How is wave speed defined?

  Distance travelled by each wave per second
• What does wave speed indicate?

  The speed at which energy is transferred by the wave
