Study Notes
Waves
- A wave is a disturbance that travels through a medium.
- Waves transfer energy, not matter.
- Examples of waves: Sound waves, light waves, water waves, radio waves, microwaves, stadium waves, earthquake waves, waves on a string, slinky waves.
Types of Waves
- Longitudinal waves: Particles vibrate parallel to the direction of the wave's motion. Example: Sound waves.
- Transverse waves: Particles vibrate perpendicular to the direction of the wave's motion. Example: Waves on a string.
Anatomy of a Wave
- Equilibrium position: The natural resting position of the medium.
- Crest: The point of maximum positive displacement from the equilibrium position.
- Trough: The point of maximum negative displacement from the equilibrium position.
