WavesWave Properties
Wave Definitions Wave
Rhythmic disturbance that transfers energy
Medium Material through which a disturbance travels
Mechanical Wave Wave that propagates through a medium
Example 1
Wave Properties Crest – highest point above the equilibrium position Trough – lowest point below the equilibrium position Amplitude – displacement of medium (from equilibrium to crest or
trough) Wavelength (λ)
Distance between two adjacent similar points of the wave (ie. crest to crest or trough to trough)
Waves are Periodic! The frequency (ƒ) is the number of complete
oscillations made in one second. Unit : Hz
The period (T) is the time taken for one complete oscillation. It is related to frequency by T = 1/ƒ Unit : s
Types of Waves Transverse
Displacement of the medium is perpendicular to motion of the wave EX: Electromagnetic Waves (EM) – light!
Longitudinal (Compressional) Displacement of the medium is parallel or anti-parallel to the motion
of the wave EX: Sound sound simulation - https://www.youtube.com/watch?v=aPswnDcteS4
