Amplitude The height of a transverse wave from the center to the crest or trough. Also measures the loudness or softness of a sound
Rarefaction The part of the longitudinal wave where the particles of the medium are far apart.
Compression The part of the longitudinal wave where the particles of the medium are close together.
Trough The lowest part of the transverse wave.
Transverse Wave A wave that moves the medium perpendicular to the direction in which the wave travels (up and down OR side to side).
Longitudinal Wave A wave that moves the medium in a direction parallel to the direction in which the wave travels (back and forth).
Wave A transfer of energy through a medium from one point to another
Frequency The number of complete waves that pass a given point in a certain amount of time.
Pitch The highness or lowness of sound
Sound A disturbance that travels through a medium as a longitudinal wave (vibration)
