Classification of Waves ,[object Object],[object Object],Conceptual Physics Chapter 25

Transverse Waves ,[object Object],Conceptual Physics Chapter 25 direction of wave travel direction of particle motion The wave propagates from left to right while the particles simply oscillate up and down – the particles do not travel with the wave!

Longitudinal Waves ,[object Object],Conceptual Physics Chapter 25 direction of wave travel direction of particle motion The wave propagates from left to right while the particles oscillate back and forth about their equilibrium positions

Slinky Waves ,[object Object],Conceptual Physics Chapter 25

Surface Waves ,[object Object],Conceptual Physics Chapter 25 As a water wave propagates from left to right across the surface of the water, the particles move in clockwise circles. The radius of the circles decreases at greater depths beneath the surface.

Standing Waves ,[object Object],Conceptual Physics Chapter 25 The easiest standing wave to produce has one segment. Shaking the rope with twice the frequency will produce a standing wave with two segments. Shaking the rope with three times the frequency will produce a standing wave with three segments.
