The following are the examples of transverse waves:
ripples on the surface of water
soundwave
vibrations in a guitar string
seismic wave
The following are the characteristics of longitudinal waves:
consists of crests and throughs
can propagate through solids, liquids, and gasses
consists of compressions and rarefactions
the vibrations are parallel to the direction of wave travel
The maximum displacement of a point of a wave from its rest position or equilibrium point is called . . . .
