Term
 is a pictoral representaion of a wave produced by simple harmonic motion.
Definition
 sine curve.
Term
 the time of a to and fro swing is called a
Definition
 period
Term
 a long pendulume has a _____1________ period then a short pendulumespeed of a pendulume will also depend on the acceleration of _________2________.
Definition
 1. longer2. Gravity
Term
 High point6s of sine curve=low points of a sine curve=
Definition
 1.crest2.through
Term
 curve that represents the crest,throughs of a wave, traced by a pendulume.
Definition
 sine curve
Term
 distance from midpoint to crest=1distance from top of one crest to top of next crest=2specifies the number of two-fro vibrations in one second.=3
Definition
 1. amplitude2.wavelength3.frequency
Term
 units of frequency are called______1________, two vibrton will equal how many of these.
Definition
 hertz
Term
 __________ of a vibration or wave is the time for one complete vibration.one is always divided by one of these numbers.
Definition
 period
Term
 energy being transfereed from source to reciever without the transfer of matter beetween the two points.
Definition
 wave motion
Term
 distance of one wavelength and the time is one period.-the formula is wavelength/period
Definition
 wave speed
Term
 up and down wave motions are called
Definition
 transverse waves.
Term
 waves that move along a stright direction across like a slinky for example.
Definition
 transverse waves.,
Term
 when waves meet is called
Definition
 wave interference
Term
 overlapping of waves______1______when wave amplitude increses and wave overlaps a through__2_when a crest overlaps a through is called _____3_____
Definition
 1.wave interference2. constructive intereference3. destructive intereference.
Term
 stationary wave pattern formecd in a medium when two sets of identical waves pass through the medium in opposire directons.
Definition
 standing wave
Term
 regions of no energy in a wave _______, maximum energy displacement ___________
Definition
 1. nodes!2. antinodes
Term
 change in frequency of a wave of sound or light due to the motion of the source or the reciever.ex. when a loud thimg is closer to you its louder, when it gets further away it gets quiter.blue shift/ red shift is what.
Definition
 doppler efffect.Increase/decrease.
Term
 when an object moves faster then sound waves
Definition
 supersonic
Term
 cone shaped wave produced by an object moving at supersonic speed through a fluid.
Definition
 shock wave
Term
 loud sound resulting from the incidence ofa shock wave.
Definition
 sonic boom
