Sound waves

• What is one way in which energy may be transferred between stores?

  Waves
• What types of waves transfer energy but not matter?

  Both mechanical and electromagnetic waves
• What are the two main types of waves discussed in the study material?

  • Longitudinal waves
  • Transverse waves
• How do sound waves cause particles to move?

  They cause particles to vibrate parallel to the direction of wave travel
• What is the speed of sound when traveling through air?

  About 330 metres per second (m/s)
• Why can't sound travel through a vacuum?

  Because there are no particles to carry the vibrations
• What are the characteristics of sound waves?

  • Sound waves are longitudinal waves
  • They cause particles to vibrate parallel to the direction of wave travel
  • They can travel through solids, liquids, or gases
• What is a medium in the context of wave propagation?

  A material through which a wave can be transmitted
• What happens to sound waves when they travel through different media?

  The speed of sound depends on the medium through which it is traveling
• What is the definition of a vacuum?

  A volume that contains no matter
• What is the relationship between sound waves and particles in a medium?

  Sound waves cause particles in the medium to vibrate
• What are the key differences between longitudinal and transverse waves?

  • Longitudinal waves: Particles vibrate parallel to wave direction
  • Transverse waves: Particles vibrate perpendicular to wave direction
