Study Notes
Mechanical Waves
- A mechanical wave is a disturbance in matter that carries energy from one location to another.
- Mechanical waves require a medium (solid, liquid, or gas) to travel through and cannot propagate through empty space.
Types of Mediums
- Solids, liquids, and gases can all serve as mediums for wave propagation.
- The medium's properties greatly influence wave behavior and speed.
Creation and Classification of Waves
- Mechanical waves are created when energy sources induce vibrations that travel through a medium.
- Mechanical waves can be classified based on their movement through the medium:
- Transverse waves: Medium vibrates at right angles to wave direction.
- Longitudinal waves: Medium vibrates parallel to wave direction.
- The classification also considers the characteristics used, such as the way waves travel through the medium.
Characteristics of Waves
- The highest point of a wave is called the crest, while the lowest point is the trough.
- In a longitudinal wave, areas where medium particles are closer together are termed compressions; areas where particles are spread out are referred to as rarefactions.
Surface Waves
- Ocean waves are classified as surface waves because they move along the boundary between air and water.
- The interaction of ocean waves with the shore causes them to transport objects as they break and roll onto the beach, influenced by friction with the bottom of shallow waters.
