Rhythmic disturbance that transfers energy

Medium Material through which a disturbance travels

Mechanical Wave Wave that propagates through a medium

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
