### CHAPTER 25 PHYSICS

Vibrations an oscillation or repeating back and fourth
wave a disturbance that repeats regularly in space and time
period the time required for a pendulum to make on to fro swing
simple harmonic motion the back and fourth vibratory motion of a swinging pendulum.
sine curve a curvve whose chape represents the crests a throughs of a wave
crest one of the places in the a wave the the higher disturbance
trough one of the places in a wave whre the wave is lowest
amplitude the distance fromt he midpoint to the maximun crst of the wave
wavelength the distance formt he top of the crest of a wave to the top of the collowing crest
frequency the number of events cycles per time
hertz the si unit of frequency
transcerse wave the wave wiht vibration at right angles
longitudinal waves a wave in which the vibration is in the same direction as that in which the wave is teveling rather then at right angles to ti
interference pattern a pattern formed by the overlapping of two or more waves at the same time
constructive interference addition of two or more waves when wave crats overlap to produce a resulting wave of invreased amplitude
destructive interference a combanation of waves where crest of one wave overlap trouphs of anohter. resulting in a wave of decreased amplitude.
out of phase term applied to two waves for which the crest of one wave arrives at a point at the smae time that a trough of the second wave arrives. their effects cancel each other.
in phase tern applied to two or more waves whose crests and troughs arrive at a place at he same time, so that thrie effects reinforce each other.
standing wave wave in which parts of the wave remain stationary and the wave appears not to be teaveling the resulf of interence between wave
node any part of a stading wave that remains stationary
antinodes the positions on a stading wabve where the largest amplitudes occur.
doppler effect the apparent change in frequency of a wabe due to the motion of the source or of the receiver.
blue shift an increase in the measured frequency of lightfrom an approaching source.
red shift the decrease in the measured frequency of light from a receding source
bow wave the v shapped wave produced by an object mobing on a liquid surface faster then the wave speed.
shock wave the cone shapped wave produced by an object moving of super sonic speed
sonic boom the sharped crack heard when the shock wave.
