Waves
Oscillation- back and forth motion that repeats itself.
Amplitude- distance from the equilbrium line to the trough or crest.
Cycle- One complete back and forth motion.
Trough- Lowest point of the wavelength.
Crest- Highest point of the wavelength.
Period- amount of time needed to complete a full cycle.
Equlibrium point- point midways between the crest and trough of the wavelength.
Frequency- the number of cycles completed every second.
