What is a wave?
A travelling disturbance that transfers energy and momentum.
Define transverse wave.
A wave where particles vibrate perpendicular to the direction of wave motion.
Define longitudinal wave.
A wave where particles vibrate parallel to the direction of wave motion.
What is amplitude?
The maximum displacement of a wave from its equilibrium position.
Define wavelength.
The distance from one repeated unit of a wave to the next.
What is the period (T) of a wave?
The time it takes for one complete cycle of a wave to occur.
What is the frequency (f) of a wave?
The number of cycles of a wave in a given amount of time.

What is amplitude?
The maximum displacement of a wave from its equilibrium value.

What is a transverse wave?
A wave where the particles vibrate perpendicular to the direction of wave motion.
What is a longitudinal wave?
A wave where the particles vibrate parallel to the direction of wave motion.
Label the parts of a transverse wave: crest, trough, wavelength, and amplitude.
Crest: Highest point of wave, Trough: Lowest point of wave, Wavelength: Distance between two crests (or troughs), Amplitude: Height from equilibrium to crest (or trough).
Label the parts of a longitudinal wave: compression, rarefaction, and wavelength.
Compression: Region of high density, Rarefaction: Region of low density, Wavelength: Distance between two compressions (or rarefactions).
