Study Notes
What is a Transverse Wave?
- A transverse wave is a wave in which the motion of the particles moves at right angles to the direction the wave is moving.
- It looks like a sine or cosine curve, with a highest point called the crest and a lowest point called the trough.
- The distance between two crests or two troughs is called the wavelength of the wave.
Examples of Transverse Waves
- Transverse waves can be made by moving one end of a string side to side or up and down.
- Examples of transverse waves include vibrations of strings on a guitar and ripples on the surface of water.
Types of Transverse Waves
- Mechanical waves require a medium to travel through and cannot travel in a vacuum.
- Electromagnetic waves do not require a medium and can transmit energy through a vacuum.
- Examples of electromagnetic waves include sunlight, radio waves, microwaves, and X-rays.
Transverse Wave vs. Longitudinal Wave
- In transverse waves, particle movement is perpendicular to the direction of the wave.
- In longitudinal waves, particle movement is parallel to the direction of the wave.
- Longitudinal waves are formed by the compression of particles, and examples include sound waves.
Longitudinal Waves
- Longitudinal waves have areas of high pressure called compressions and areas of low pressure called rarefactions.
- The wavelength of longitudinal waves can be determined by measuring the distance between two compressions or two rarefactions.
Longitudinal and Transverse Wave Diagrams
- Longitudinal and transverse waves both transfer energy from one place to another, but they do it in different ways.
Longitudinal and Transverse Wave Movement
- Transverse waves only move through solids, while longitudinal waves can move through solids, liquids, and gases.
Examples of Longitudinal and Transverse Waves
- Earthquakes produce both longitudinal (P waves) and transverse (S waves) waves, which helped determine that the Earth's core consists of a liquid.
- Rayleigh waves are a combination of transverse and longitudinal waves, with both vertical and horizontal components to their direction.
- Surface waves, such as ocean waves, are also a combination of longitudinal and transverse waves.
