Study Notes
Waves
- All waves are categorized into transverse and longitudinal waves.
- Waves transfer energy from one location to another.
- Ripples transfer kinetic energy; sound waves transfer sound energy.
Transverse Waves
- Oscillations are perpendicular to the direction of energy transfer.
- Ripples are an example of transverse waves: oscillations are up and down, while energy travels sideways.
- Not all transverse waves need a medium.
Longitudinal Waves
- Oscillations are parallel to the direction of energy transfer.
- Sound waves are an example, with air particles moving back and forth, creating compressions (tightly packed particles) and rarefactions (spread-out particles).
- All longitudinal waves require a medium (like air, liquid, or solid) to travel through.
Key Fact
- The wave travels, not the medium.
- This can be seen with a slinky: a single point (an air particle, or water molecule) oscillates but doesn't move through the medium.
