sine curve
the waveform traced by simple harmonic motion, which can be made visible on a moving conveyor belt by a pendulum swinging at right angles above the moving belt
amplitude
for a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position
wavelength
the distance between successive crests, troughs, or identical parts of a wave
frequency
for a vibrating body of medium, the number of vibrations per unit time; for a wave, the number of crests that pass a particular point per unit time
hertz
SI unit of frequency
period
the time in which a vibration is completed
wave speed
the speed at which waves pass a particular point
transverse wave
a wave in which the medium vibrated 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
wave interference
phenomenon that occurs when two waves meet while traveling along the same medium
interference pattern
the pattern formed by the superposition of different sets of waves the produces reinforcement in some places and cancellation of others
