Study Notes
Classification of Waves
- Waves can be classified based on what they move through: mechanical and electromagnetic.
- Mechanical waves require a medium for energy transfer, while electromagnetic waves can travel through matter or empty space.
Mechanical Waves
- Examples include water waves, seismic waves, sound waves, and waves on a rope or string.
- Sound waves are classified specifically as mechanical waves.
Electromagnetic Waves
- Electromagnetic waves encompass a range of wave types and do not necessitate a medium for propagation.
- Visible light is a segment of the electromagnetic spectrum that is perceivable by the human eye.
Wave Movement Classification
- Waves are classified by their motion into longitudinal and transverse categories.
Longitudinal Waves
- These waves vibrate by compressing and expanding particles in the same direction as the wave travels.
- Components of longitudinal waves include compressions (areas where particles are pushed together) and rarefactions (areas where particles are moving apart).
- Examples include sound waves and primary seismic waves, which are always classified as mechanical waves.
Transverse Waves
- In these waves, particles move back and forth perpendicular to the direction of wave travel.
- The highest point is referred to as the crest, while the lowest point is known as the trough.
- Examples include slinky springs, waves on a rope, strings on musical instruments, and secondary seismic waves.
- All electromagnetic waves are classified as transverse waves.
