Wave A disturbance that transfers energy from place to place
Energy The ability to do work or cause change
Amplitude The maximum distance the particles of a medium move away from their rest position as a wave through the medium
Wavelength The distance between two corresponding parts of a wave
Frequency The number of complete waves that pass a given point in a certain amount of time
Vibration A repeated back-and-forth or up-and-down motion
Crest The highest part of a converse wave
Trough The lowest part of the converse wave
Resting Position The position in which the wave would sit if there was no disturbance moving through it
Mechanical Waves A wave that must travel through a medium in order to be transferred
Medium The material through which a wave travels
Damping A decrease in amplitude as energy decreases because of gravity, air resistance, friction, etc.
