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.
