### vibrations, waves, and sounds

TermDefinition
Amplitude (volume) For a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position.
Wavelength The distance between successive crest, troughs, or identical parts of a wave
Frequency (pitch) for a vibrating body or medium, the number of vibrations per unit time. For a wave, the number of crests that pass a particular point per unit time.
period the time in which a vibration is completed. The period of a wave equals the period of the source, and is equal to 1/frequency.
Period of a Pendulum T=2(Pi)sqrt(L/g)
transverse wave a wave in which the medium vibrates in a direction perpendicular to the direction in which the wave travels.
longitudinal wave a wave in which the medium vibrates in a direction parallel to the direction in which the wave travels.
velocity formula wavelength x frequency = speed V=FY (wavelength-Y)(frequency-F)
frequency formula 1/period
