Study Notes
Waves
- A wave is a vibration or disturbance in space.
- A wave is a form of energy transfer.
Types of Waves
- Mechanical waves need a medium to propagate.
- Examples: water waves, sound waves
- Electromagnetic waves do not need a medium to propagate.
- Examples: x-rays, radio waves, light
Direction of Propagation
- Waves can be categorized based on the direction of propagation.
- Transverse waves: particles of the medium oscillate perpendicular to the motion of the wave.
- Examples: water waves, electromagnetic waves traveling in a medium
- Longitudinal waves: particles of the medium oscillate parallel to the motion of the wave.
- A longitudinal wave has two main sections:
- Compression: an area of high molecular density and pressure
- Rarefaction: an area of low molecular density and pressure
- A longitudinal wave has two main sections:
