|
amplitude
|
the height of a wave from the equilibrium position (from line to top or bottom of the parabola).
|
|
|
crest
|
the high point of a wave.
|
|
|
frequency
|
the number of waves per unit time.
|
|
|
longitudinal wave (aka P Wave)
|
wave where the motion of the medium is parallel to the direction of the wave.
|
|
|
antinode
|
point of maximum displacement of the wave medium. (top or bottom of parabola).
|
|
|
constructive interference
|
when waves interact to reinforce each other.
|
|
|
destructive interference
|
when waves interact to destroy each other.
|
|
|
node
|
point of little or no motion (where wave hits the mid-line).
|
|
|
standing wave
|
a non-traveling wave form.
|
|
|
transverse wave (aka S Waves)
|
wave where the motion of the medium is perpendicular to the direction of the wave.
|
|
|
trough
|
the low point of a wave.
|
|
|
wave
|
a transfer of energy, NOT MATTER
|
|
|
wavelength
|
the distance from any point on a wave to the same point on a successive wave.
|
|
|
wave pulses
|
a single disturbance traveling through a medium.
|
|
|
the larger the object...
|
...the lower the pitch.
|
|
|
equal wave + equal wave =
|
reinforcement
|
|
|
one wave + opposite wave =
|
cancellation
|
|
|
one wave + a different wave =
|
partial cancellation
|
|
|
P-Waves
|
primary, push/pull, pressure --> longitudinal
|
|
|
S-Waves
|
secondary, shearing, scissoring --> transverse
|
|
|
period
|
the time it takes for something to happen. the time it takes for ONE wave oscillation. the time for one wave (a crest and a trough) to pass a given point.
|
|
|
frequency
|
the number of times something happens in a given unit of time. #waves/second OR #vibrations/unit time OR #oscillations/second OR #cycles/second = HERTZ = 1/second SO 1Hz = 1/s
