Transverse Waves

Definition: A wave where particle motion is perpendicular (at right angles) to the wave's direction of travel. This is the most common wave type.
Appearance: Resembles a sine or cosine curve.
Cycle Components:
- Crest: Highest point of the wave.
- Trough: Lowest point of the wave.
- Wavelength: Distance between two consecutive crests or troughs.
Mechanical Waves: Require a medium (e.g., string, water) for travel. Particles in the medium move in a transverse direction, as the wave passes through the medium. Examples include waves on a string, guitar strings, and water ripples.
Electromagnetic Waves: Do not require a medium. Created by vibrating electric and magnetic fields. Examples include light, radio waves, microwaves, and X-rays.
Transverse vs. Longitudinal: In transverse waves, particle movement is perpendicular to wave movement; in longitudinal waves, particle movement is parallel to wave movement.

Wave Types and Characteristics

Longitudinal wave: Particle movement is parallel to the wave's direction of travel. Characteristics include compressions (high-pressure areas) and rarefactions (low-pressure areas). Examples include sound waves.
Comparison: Transverse waves move through solids, longitudinal waves move through solids, liquids, and gases.
Combination Waves: Some waves, like Rayleigh waves (earthquakes) and surface water waves, have both transverse and longitudinal components of motion (combined movement). These waves move both perpendicular and parallel to the wave direction. This complex movement describes the wave.
