a disturbance that transfers energy away from the source in all directions
a wave where the energy travels at right angles (perpendicular) to the disturbance
a wave where the energy travels in the same direction as the disturbance
a wave that requires a medium through which to travel
the material through which a wave travels
the highest point of a transverse wave
the lowest point of a transverse wave
the part of a longitudinal wave where the particles of the medium are closest together
examples of transverse waves
