Wave types and how waves transfer energy

Waves and electromagnetic radiation • Properties of waves

Key concepts

What you'll likely be quizzed about

  • Mechanical waves require a medium to travel through, such as air, water, or solids.
  • Sound waves are a prime example, as they propagate through vibration of particles in the medium.
  • These waves transfer energy by causing molecules in the medium to vibrate, which in turn transfers energy to neighboring molecules, creating a wave-like motion.
