Waves
![Page 2: Waves. Definitions Wave: a disturbance that transfers energy through a medium. The matter does not experience net movement, but vibrates about some rest.](https://reader036.fdocuments.us/reader036/viewer/2022082911/5a4d1bb27f8b9ab0599ccef3/html5/thumbnails/2.jpg)
Definitions• Wave: a disturbance that transfers
energy through a medium. The matter does not experience net movement, but vibrates about some rest position.
• Mechanical Wave: waves that travel through matter.

Common Characteristics of All Waves

Common Characteristics of All Waves
• Crests: the highest points• Troughs: the lowest points• Amplitude: the distance between the rest
position and a crest or trough

Common Characteristics of All Waves
• Wavelength (λ, lambda): the shortest distance between two points in the medium that are in phase
• Frequency (f): the number of complete wavelengths that pass a point in a given time. (Unit: Hertz, Hz)
• Period (T): the time it takes for one full wavelength to pass a given point.

Types
• Transverse Wave: the particles of the medium vibrate at right angles to the direction of motion (example: water waves)
• Longitudinal Waves: the particles of the medium vibrate parallel to the direction of the motion (example: sound waves)

Universal Wave Equation
• The form of the equation v=∆d/Δt for waves
• The speed of a wave is the product of the wavelength and the frequency
v= fλ
