|
antinode
|
pooints of constructive interference;
where cord oscillates with maximum amplitude |
|
|
node
|
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.
|
|
|
interference
|
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)
|
|
|
reflection
|
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.
|
|
|
amplitude
|
(A) maximum displacement from the equilibrium position.
|
|
|
wavelength
|
(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).
|
|
|
pulse
|
a single wave bump
|
|
|
resonant frequency
|
the natural vibrating frequency of a system
|
|
|
resonance
|
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.
|
|
|
rarefractions
|
expansions in a longitudinal wave
|
|
|
compressions
|
compressed part of a longitudinal wave.
|
|
|
crest
|
when transverse wave is above equilibrium position.
|
|
|
trough
|
when transverse wave is below equilibrium position.
