Unit 4: Waves and Sound Flashcards
Vibration
cyclical motion of an object about an equilibrium point
mechanical wave
the transfer of energy through a material due to vibration
medium
the material that permits the transmission of energy through vibrations
net motions
the displacement of a particle over a certain time interval; the difference between the particles initial and final positions
elastic
the property of a medium that returns to its original shape after being disturbed
translational molecular motion
the straight line motion of a molecular; this motion is typical of gases because the particles In liquids and solids are not free to move in this manner
transverse wave
a wave in which particles vibrate perpendicular to the direction of the flow of energy
longitudinal wave
a wave in which particles vibrate parallel to the direction of the flow of energy
compression
the region in longitudinal wave in which the medium particles are closer together
rarefaction
the region in longitudinal wave in which the mediums particles are father apart
sound
a form of energy produced by rapidly vibrating objects detectable by sensory organs as the ears
amplitude
the maximum displacement of a wave from is equilibrium
wave form
the shape of a wave when graphed
crest
the maximum point of a transverse wave
through
the minimum point of a transverse wave
