sound is a ____________ wave in which particles in the medium move - Correct
answer-mechanical
where can sound not travel - Correct answer-in a vacuum
are sound waves transverse or longitudinal waves - Correct answer-longitudinal
the effects of the medium upon the sound wave - Correct answer-acoustic
propagation properties
what are used to distinguish between sound waves and other types of waves -
Correct answer-acoustic variables- pressure, density, and distance (measure of a
particle motion)

,concentration of force in an area - Correct answer-pressure
what is pressure measured in - Correct answer-pascals (Pa)
concentration of mass in a volume - Correct answer-density
what is volume measured in - Correct answer-kg/cm^3 (cubic)
what describes a sound waves features - Correct answer-acoustic parameters
what are the 7 acoustic parameters - Correct answer-period, frequency, amplitude,
power, intensity, wavelength, propagation speed
how do particles move in soundwaves - Correct answer-longitudinally- particles
move in the same direction that the wave propagates (parallel)
in-phase wave - Correct answer-when their peaks and troughs occur at the same
time
out of phase wave - Correct answer-peaks and troughs occur at difference times
-either inverted or out of step
what occurs when waves lose their individual characteristics and combine to form
a single wave - Correct answer-interference
what combination of waves results in the formation of a single wave of greater
amplitude of either components - Correct answer-constructive interference

, what kind of wave causes the formation of a single wave of lesser amplitude
causing what types of interference - Correct answer-out of phase
destructive interference
what occures when 2 out of phase waves of equal amplitude interfere - Correct
answer-complete destructive interference
what types of waves (phase) occur with complete destructive interference - Correct
answer-out of phase waves
what causes waves to be momentarily in phase and out of phase (causing
constructive and destructive interference) - Correct answer-waves of difference
frequencies
what type of waves of difference frequencies result in (type of interference) -
Correct answer-constructive and destructive
what direction of the graph is verticle vs horozontal - Correct answer-y=vertical
x=horozonatal
what is a reciprocal - Correct answer-when the 2 numbers are multiplied together
to = 1
(10 x 1/10)
