pooints of constructive interference;
where cord oscillates with maximum amplitude
points of destructive interference;
where cord remains still
standing wave
a pattern thta is produced by interaction of incident and reflected waves.
principle of superposition
to determine the resulting amplitude when waves interfere, add the individual amplitudes together.
destructive interference
result of when two waves oppose each other as they pass by.
constructive interference
when the resulting wave has an amplitude greater than that of either of the orginal waves.
the interaction of different waves of the same nature.
wave fronts
the whole width of a wave crest (what we call a "wave" when at the beach)
a wave that has bounced back from a boundary between two different materials
transverse wave
a wave in which the direction of the vibration is PERPENDICULAR to direction of traveling motion of wave.
longitudinal wave
a wave in which the direction of the vibration is PARALLEL to direction of traveling motion of wave.
(A) maximum displacement from the equilibrium position.
(lambda sign) the distance between two successive crests
wave velocity
the velocity at which wave crests (or any other part of the waveform) moves.
continuous/periodic wave
the source of the wave is a vibration (or oscillation).
a single wave bump
resonant frequency
the natural vibrating frequency of a system
occurs when periodic impulses are given to an object ata frequency equal to one of its natural frequencies of oscillation.
natural frequency
the frequency at which a system would vibrate if disturbed and then left alone.
forced vibration
when a system has an external force applied to it that has its own particular frequency.
expansions in a longitudinal wave
compressed part of a longitudinal wave.
when transverse wave is above equilibrium position.
when transverse wave is below equilibrium position.
