TermDefinition
Wave A disturbance that travels through a medium from one location to another
Harmonic Motion Motion that repeats periodically
Transverse wave A wave vibrating at right angles to the direction of energy movement.
Longitudinal wave A wave vibrating in the same direction as the energy moves.
Velocity The speed of an object in a given direction.
Frequency The number of waves that pass a fixed place in a given amount of time.
Hertz Unit of frequency; number of waves per second.
Period Number of seconds per one wave cycle
Amplitude The maximum extent of a vibration measured from equilibrium.
Wavelength Distance between successive crests (or same point) on a wave
Electromagnetic wave Transverse waves composed of perpendicular oscillating electric and magnetic fields.
Electromagnetic Spectrum Range of wavelengths or frequencies over which electromagnetic radiation extends.
Medium The substance that waves travel through.
Crest The highest point on a transverse wave.
Trough The lowest point on a transverse wave.
Compression The region in a longitudinal wave where the particles are closest together.
Rarefaction The region in a longitudinal wave where the particles are farthest apart.
