Introduction to Waves

3:43 Types of Wave
Spec 4.6.1.1
Previous Structure of the Earth Next Transverse Waves
  • Waves transport energy from one place to another.
  • Types of waves include light waves, seismic waves, and waves on a rope.
  • Speakers produce sound waves that transport energy to our ears.
  • Sound waves cause bones in the ear to vibrate, allowing the brain to interpret sound.
  • Waves can also transport information, such as the characteristics of sound.
  • Water waves, like ripples from a raindrop, transport kinetic energy across water.
  • Mechanical waves are transported through the movement of matter.
  • Mechanical waves include all types except electromagnetic (EM) waves, such as light.
  • Sound waves are mechanical waves, moving through air molecules.
  • Energy in sound waves causes molecules to move, transferring energy to the next molecule.
  • Matter does not move permanently as waves pass; it returns to its original position.
  • This principle applies to all waves, mechanical and non-mechanical.
