Study Notes
Sound and Waves
- Sound is an energy form generated through vibration, transmitting energy from one location to another through a medium (solid, liquid, or gas).
- Sound waves are characterized by alternating compressions and rarefactions.
- Compressions signify an increase in pressure or density, while rarefactions occur during the troughs of the sound wave.
Types of Waves
- Mechanical Waves:
- Defined by the disturbance of a physical medium.
- Examples include:
- Ocean waves
- Sound waves
- Seismic waves
- Electromagnetic Waves (transverse wave):
- Do not require a medium and can propagate through a vacuum.
- Examples include:
- Radio waves
- X-rays
- Light
Longitudinal Waves
- Particle displacement occurs parallel to the wave's direction of energy movement.
- Requires an initial vibration from a source object.
- Requires a material for wave travel.
Transverse Waves
- Particle displacement occurs perpendicular to the wave's direction of propagation.
- Example: Electromagnetic Waves
Speed of Light
- Velocity is relatively constant at approximately 299,792.456.2 m/s in a vacuum.
Acoustic Parameters
- Key parameters to consider in sound waves include:
- Frequency
- Period
- Wavelength
- Propagation Speed
- Amplitude
- Power
- Intensity
