SONOGRAPHY CANADA PHYSICS CORE EXAM
QUESTIONS AND ANSWERS GRADED A+ 100% VERIFIED.
what is media/medium ANS >>> biological tissue
what do all waves carry from one location to another
ANS >>> energy
sound is a ____________ wave in which particles in the
medium move ANS >>> mechanical
where can sound not travel ANS >>> in a vacuum
,are sound waves transverse or longitudinal waves ANS
>>> longitudinal
the effects of the medium upon the sound wave ANS
>>> acoustic propagation properties
what are used to distinguish between sound waves and
other types of waves ANS >>> acoustic variables-
pressure, density, and distance (measure of a particle
motion)
what are the 3 acoustic variables ANS >>> pressure,
density and distance
concentration of force in an area ANS >>> pressure
what is pressure measured in ANS >>> pascals (Pa)
concentration of mass in a volume ANS >>> density
,what is volume measured in ANS >>> kg/cm^3 (cubic)
what describes a sound wave features ANS >>> acoustic
parameters
what are the 7 acoustic parameters ANS >>> period,
frequency, amplitude, power, intensity, wavelength,
propagation speed
how do particles move in soundwaves ANS >>>
longitudinally- particles move in the same direction that
the wave propagates (parallel)
in-phase wave ANS >>> when their peaks and troughs
occur at the same time
out of phase wave ANS >>> 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 ANS
>>> interference
what combination of waves results in the formation of a
single wave of greater amplitude of either component
ANS >>> constructive interference
what kind of wave causes the formation of a single wave
of lesser amplitude causing what types of interference
ANS >>> out of phase
destructive interference
what occurs when 2 out of phase waves of equal
amplitude interfere ANS >>> complete destructive
interference
what types of waves (phase) occur with complete
destructive interference ANS >>> out of phase waves
