Study Notes
Vibration
- Vibration is the repeated back-and-forth motion of a particle from its equilibrium position.
- This oscillatory motion is periodic, occurring at regular time intervals.
- Examples include vibrating tuning forks, pendulums, and loudspeaker oscillations.
- Vibrations create sound by displacing medium particles back and forth parallel to the wave direction.
Vibration and Waves
- Vibrations are the sources of waves.
- Waves are disturbances that transfer energy from one point to another.
- Examples include sound waves, water waves, and light.
Types of Waves
- Transverse waves: Particles vibrate perpendicular to wave propagation. Light is an example.
- Longitudinal waves: Particles vibrate parallel to wave propagation. Sound waves are an example.
Mechanical vs. Electromagnetic Waves
- Mechanical waves: Require a medium to propagate. Examples include waves on strings or slinkies and sound waves.
- Electromagnetic waves: Do not require a medium and can travel through a vacuum. Examples include radio waves, microwaves, visible light, X-rays, and gamma rays.
Parts of a Wave
- Crest: Highest point of a wave.
- Trough: Lowest point of a wave.
- Wavelength: Distance between two successive identical points (e.g., crests or troughs).
- Amplitude: Distance between the equilibrium position and the highest or lowest point.
- Frequency: Number of waves passing a fixed point per second, measured in Hertz (Hz). Wavelength and frequency are inversely related.
Wave Energy Transfer
- Waves transfer energy, not matter.
- In sound waves, air particles vibrate but return to their original position after the energy passes.
- The amplitude of a wave corresponds to the energy it carries. Larger amplitude means more energy.
