All waves carry _______ from one location to another. - ANSWER energy
Sound is a __________ wave in which particles in the medium move. -
ANSWER mechanical
Can sound travel through a vacuum? - ANSWER No. Sound must travel through
matter and there is no matter in vacuums.
there are areas of ______ and ______ in a sound wave - ANSWER
compression, rarefraction
in what way does sound travel? - ANSWER in a straight line
Sound waves are _____ waves. - ANSWER longitudinal
Acoustic propagation properties are? - ANSWER the effects of the medium
upon the sound wave
Acoustic variables - ANSWER changes that occur within a medium as a result of
sound traveling through that medium
What are the 3 acoustic variables? - ANSWER Pressure (P), density (ρ), and
distance (particle vibration)
,what is the acoustic variable pressure ? - ANSWER concentration of force in an
area
units: pascals (Pa)
what is the acoustic variable density? - ANSWER concentration of mass in a
volume
units: kg/cm^3
what is the acoustic variable distance? - ANSWER measure of particle motion
units: cm, feet, mile
what does one of the acoustic variables have to do in order to be a sound wave? -
ANSWER rhythmically oscillate
sound waves are also known as ____ waves - ANSWER acoustic
What are the 7 acoustic parameters? - ANSWER 1. Period
2. Frequency
3. Amplitude
4. Power
5. Intensity
6. Wavelength
7. Propagation speed
, How do particles move in a transverse waves? - ANSWER perpendicular to the
wave propagation
(ex: hold end of string and shake up and down)
how do particles move in longitudinal waves? - ANSWER in the same direction
that the wave propagates.
sound is a longitudinal wave.
what are considered in-phase waves? - ANSWER a pair of waves that have their
peaks at the same time and same location
what are considered out-of-phase waves? - ANSWER a pair of waves that have
their peaks at different points and at different times
what kind of interference occurs with in-phase waves? - ANSWER constructive
interference
what kind of interference occurs with out-phase waves? - ANSWER destructive
interference
what is interference (for sound)? - ANSWER when more than one sound beam
travel in a medium and can arrive at the same place at the same time. the waves
then loose their individual characteristics and combine to form a single wave.
