Study Notes
Properties of Waves
- High amplitude sound waves are perceived as louder compared to low amplitude waves.
- Wavelength is defined as the distance between similar points on a wave, such as from one trough to the next.
- Frequency measures how many waves pass a given point in a specified time period; high frequency corresponds to a higher pitch.
- More frequent waves tend to have shorter wavelengths.
Types of Waves
- Transverse Wave: Moves perpendicular to the direction of particles, characterized by crests (top) and troughs (bottom).
- Longitudinal Wave: Moves parallel to the direction of the particles, involving compression and expansion.
Wave Energy
- Waves are a means of transferring energy without relocating medium particles; energy is carried through a medium.
- Vibrations of particles generate waves; movement can be back and forth, contributing to energy transfer.
Wave Characteristics
- Amplitude: The height from the resting position to the crest, indicating energy levels in the wave.
- Wavelength: The spatial repeat distance of similar points on a wave.
- Frequency: The rate at which waves repeat within a certain timeframe.
Types of Waves and Medium
- Various waves include light, sound, surface ripples, and seismic tremors; all travel in repeating patterns and carry energy.
- Light waves can travel through a vacuum, while sound waves and other types require a medium (like air or water).
- Light waves travel faster than sound or mechanical waves.
