- Waves
- Transfer energy from one place to another without transferring matter
- Transverse
- The oscillations (vibrations) are PERPENDICULAR (at 90 degrees) to the DIRECTION of energy transfer.
- Most waves are transverse
- Electromagnetic Waves e.g light
- Ripples and waves in water
- A wave on a string
- Longitudinal
- The oscillations are PARALLEL to the DIRECTION of energy transfer.
- Sound waves in air, ultrasound
- Shock waves e.g some seismic waves
- The oscillations are PARALLEL to the DIRECTION of energy transfer.
- Wave Speed
- Frequency multiplied by wave length
