Study Notes
Waves
Ocean Waves
- Caused by wind friction on the surface of the ocean
- Transfer energy from one location to another
- Characteristics:
- Wavelength: distance between two consecutive wave crests
- Frequency: number of waves passing a point per second
- Amplitude: maximum height of the wave above the calm water level
- Speed: depends on wavelength and water depth
Sound Waves
- Mechanical waves that propagate through a medium (solid, liquid, or gas)
- Produced by vibration of an object
- Characteristics:
- Frequency: pitch of the sound
- Wavelength: distance between two consecutive compressions or rarefactions
- Amplitude: loudness of the sound
- Speed: approximately 343 m/s in air at room temperature and atmospheric pressure
Light Waves
- Electromagnetic waves that transmit energy through electromagnetic fields
- Produced by vibration of charged particles
- Characteristics:
- Wavelength: varies from 400-700 nanometers (visible light)
- Frequency: related to energy and color
- Amplitude: intensity of the light
- Speed: approximately 299,792,458 m/s in a vacuum
Electromagnetic Waves
- Waves that propagate through electromagnetic fields
- Produced by acceleration of charged particles
- Characteristics:
- Wavelength: ranges from gamma rays (<0.1 nm) to radio waves (>1 m)
- Frequency: related to energy and wavelength
- Amplitude: intensity of the radiation
- Speed: approximately 299,792,458 m/s in a vacuum
- Applications: radio communication, medical imaging, heating, and lighting
Seismic Waves
- Mechanical waves caused by the vibration of the Earth's interior
- Produced by earthquakes, volcanic eruptions, or human activities
- Characteristics:
- P-waves (primary waves): compressional waves that travel through solid, liquid, and gas
- S-waves (shear waves): shear waves that travel through solid media only
- Surface waves: waves that travel along the Earth's surface
- Speed: varies depending on the type of wave and the medium
