Waves Wave Properties Waves are propagated by a vibrating source Pulse – single disturbance created by a single oscillation Periodic Wave – periodic.

Properties of Waves Objectives:

WAVES Wave - a periodic disturbance that propagates energy through a medium or space, without a corresponding transfer of matter. e.g.1 sound wave (regular.

Review: What’s the difference between a transverse and longitudinal wave? What do waves transfer? What are the high and low points of a transverse wave.

Transverse & Longitudinal Waves. Transverse Waves The definition of transverse wave is a wave moving across or perpendicular to the direction that the.

What are waves? a disturbance that transfers energy from place to place. Classified as either 1. Mechanical- require a medium 2. Electromagnetic- do not.

Parts of a Wave

Crest Point of maximum displacement trough crest

Trough Point of minimum displacement trough crest

Amplitude Greatest distance from natural resting position NOT vertical distance from crest to trough amplitude trough crest

Wavelength Distance between two equivalent parts of the wave Units: m Symbol: λ (lambda) or Crests

Period Time required for one full λ to pass a given point Units: seconds Symbol: T

Frequency Number of λ that pass a certain point during a given time interval. Units: hertz (Hz), or 1/s (cycles per second) Symbol: f or Crests

On a longitudinal wave Compression: particles are closest together Rarefraction: particles are spread farthest apart compressionrarefaction
